Our method is based on the Criminisi pipeline. We focused on three main stages of the pipeline; calculation of priorities, construction of patches, and the search for the best match. To assign a high priority to patches constructed from the edge pixels, we use the ability of segmentation algorithms to divide an image into different texture blocks. The patches built from pixels located at the border between several texture blocks receive a high priority. Unlike most patch-based image inpainting methods which use regular patches (rectangle, square), the shape and size of our patches depend on the textural composition around the original pixel. The patches are built using a region growing principle in the different texture blocs around the original pixel. The search for the best match is done contextually. We search for the best match of the patch with the highest priority in a similar environment to its neighborhood around the target zone. The method is simple and easy to implement. The experiments show that our method obtains more plausible results than the basic method of Criminisi and its improved version Amoeba in most cases.}, language = {en} } @misc{SchorradtCastilloCunningham, author = {Schorradt, Martin T. and Castillo, Susana and Cunningham, Douglas William}, title = {The Semantic Space for Emotional Speech and the Influence of Different Methods for Prosody Isolation on Its Perception}, series = {SAP '18: Proceedings of the 15th ACM Symposium on Applied Perception}, journal = {SAP '18: Proceedings of the 15th ACM Symposium on Applied Perception}, publisher = {Association for Computing Machinery}, address = {New York, NY, United States}, isbn = {978-1-4503-5894-1}, doi = {10.1145/3225153.3225156}, pages = {1 -- 8}, language = {en} } @misc{HahnCastilloCunningham, author = {Hahn, Philipp and Castillo, Susana and Cunningham, Douglas William}, title = {Fitting the Style: The Semantic Space for Emotions on Stylized Faces}, series = {CASA '19: Proceedings of the 32nd International Conference on Computer Animation and Social Agents}, journal = {CASA '19: Proceedings of the 32nd International Conference on Computer Animation and Social Agents}, publisher = {Association for Computing Machinery}, address = {New York, NY, United States}, isbn = {978-1-4503-7159-9}, doi = {10.1145/3328756.3328770}, pages = {21 -- 24}, language = {en} } @misc{LegdeCunningham, author = {Legde, Katharina and Cunningham, Douglas William}, title = {Evaluating the Effect of Clothing and Environment on the Perceived Personality of Virtual Avatars}, series = {IVA '19: ACM International Conference on Intelligent Virtual Agents}, journal = {IVA '19: ACM International Conference on Intelligent Virtual Agents}, publisher = {Association for Computing Machinery}, address = {New York, USA}, isbn = {978-1-4503-6672-4}, doi = {10.1145/3308532.3329425}, pages = {206 -- 208}, language = {en} } @misc{KoulierisDrettakisCunninghametal., author = {Koulieris, George Alex and Drettakis, George and Cunningham, Douglas William and Sidorakis, Nikolaos and Mania, Katerina}, title = {Context-awarematerial selective rendering for mobile graphics}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-4503-2958-3}, doi = {10.1145/2614217.2614246}, pages = {1}, language = {en} } @misc{KoulierisDrettakisCunninghametal., author = {Koulieris, George Alex and Drettakis, George and Cunningham, Douglas William and Mania, Katerina}, title = {C-lod: Context-aware material level-of-detail applied to mobile graphics}, series = {Computer Graphics Forum}, volume = {33}, journal = {Computer Graphics Forum}, number = {4}, issn = {1467-8659}, doi = {10.1111/cgf.12411}, pages = {41 -- 49}, language = {en} } @misc{KoulierisDrettakisCunningham, author = {Koulieris, George Alex and Drettakis, George and Cunningham, Douglas William}, title = {An automated high level saliency predictor for smart gane balancing}, series = {ACM Transactions on Applied Perception : (TAP)}, volume = {11}, journal = {ACM Transactions on Applied Perception : (TAP)}, number = {4}, issn = {1544-3965}, pages = {17-1 -- 17-21}, language = {en} } @misc{CastilloWallravenCunningham, author = {Castillo, Susana and Wallraven, Christian and Cunningham, Douglas William}, title = {The semantic space for facial communication}, series = {Computer Animation and Virtual Worlds}, volume = {25}, journal = {Computer Animation and Virtual Worlds}, number = {3-4}, issn = {1546-427X}, pages = {223 -- 231}, language = {en} } @misc{SchorradtCunningham, author = {Schorradt, Martin T. and Cunningham, Douglas William}, title = {Age Regression for Human Voices}, series = {ICMI '22: INTERNATIONAL CONFERENCE ON MULTIMODAL INTERACTION Bengaluru India November 7 - 11, 2022}, journal = {ICMI '22: INTERNATIONAL CONFERENCE ON MULTIMODAL INTERACTION Bengaluru India November 7 - 11, 2022}, editor = {Tumuluri, Raj and Sebe, Nicu and Pingali, Gopal and Jayagopi, Dinesh Babu and Dhall, Abhinav and Singh, Richa and Anthony, Lisa and Salah, Albert Ali}, publisher = {Association for Computing Machinery New York NY United States}, isbn = {978-1-4503-9390-4}, doi = {10.1145/3536221.3556599}, pages = {570 -- 578}, abstract = {The human voice is one of our most important tools for communicating with other people. Besides pure semantic meaning it also conveys syntactical information such as emphasis as well as personal information such as emotional state, gender, and age. While the physical changes that occur to a person's voice are well studied, there is surprisingly little work on the perception of those changes. To hold the range of subtleties present in a given utterance constant and thus focus on the changes caused by age, this paper takes adult recordings (three males, and three females) and artificially resynthesizes them (using values from measurements of real children's voices) to create a childlike versions of the utterance at different target ages. In particular, we focus on a systematic, factorial combination pitch shifting and formant shifting. To get an insight about the influence of these factors on the estimated age, we performed a perceptual experiment. Since the resynthesis method we used can produce a wide range of voices, not all of which are physically consistent, we also asked the participants to rate how natural the voices sounded. Furthermore, since former studies suggest that people are not able to distinguish between males and females of young ages, participants were also asked to rate how male or female the voices sounded. Overall, we found that although the synthesis method produced physically plausible signals (compared average values for real children), the degree of signal manipulation was correlated with perceived unnaturalness. We also found that pitch shift had only a small affect on perceived age, that formant shift had a strong affect on perceived age, and that these effects depended on the original gender of the recording. As expected, people had difficulty guessing the gender of younger sounding voices.}, language = {en} } @misc{SterzikLichtenbergKroneetal., author = {Sterzik, Anna and Lichtenberg, Nils and Krone, Michael and Cunningham, Douglas William and Lawonn, Kai}, title = {Perceptual Evaluation of Common Line Variables for Displaying Uncertainty on Molecular Surfaces}, series = {Eurographics Workshop on Visual Computing for Biology and Medicine}, journal = {Eurographics Workshop on Visual Computing for Biology and Medicine}, editor = {Raidou, Renata G. and Sommer, Bj{\"o}rn and Kuhlen, Torsten W. and Krone, Michael and Schultz, Thomas and Wu, Hsiang-Yun}, publisher = {The Eurographics Association}, isbn = {978-3-03868-177-9}, issn = {2070-5786}, doi = {10.2312/vcbm.20221186}, pages = {41 -- 51}, abstract = {Data are often subject to some degree of uncertainty, whether aleatory or epistemic. This applies both to experimental data acquired with sensors as well as to simulation data. Displaying these data and their uncertainty faithfully is crucial for gaining knowledge. Specifically, the effective communication of the uncertainty can influence the interpretation of the data and the users' trust in the visualization. However, uncertainty-aware visualization has gotten little attention in molecular visualization. When using the established molecular representations, the physicochemical attributes of the molecular data usually already occupy the common visual channels like shape, size, and color. Consequently, to encode uncertainty information, we need to open up another channel by using feature lines. Even though various line variables have been proposed for uncertainty visualizations, they have so far been primarily used for two-dimensional data and there has been little perceptual evaluation. Therefore, we conducted a perceptual study to determine the suitability of the line variables sketchiness, dashing, grayscale, and width for distinguishing several uncertainty values on molecular surfaces.}, language = {en} } @misc{SchorradtCunningham, author = {Schorradt, Martin T. and Cunningham, Douglas William}, title = {Erosion as a novel Approach for removing Semantics and Comparison of different State-of-Art-Methods}, series = {SAP '22: ACM Symposium on Applied Perception 2022}, journal = {SAP '22: ACM Symposium on Applied Perception 2022}, editor = {Lau, Manfred and Robb, Andrew and Barnett-Cowan, Michael and Serrano, Ana and Malpica, Sandra}, publisher = {Association for Computing Machinery New York NY United States}, isbn = {978-1-4503-9455-0}, doi = {10.1145/3548814.3551458}, pages = {1 -- 6}, abstract = {Through language, people convey not only pure semantics, but also information about themselves, such as age, gender, state of mind or health.

In this paper, we propose a new method for removing sematics, based on erosion, a morphological operator. We compare its effectiveness to different state-of-the-art methods. As established methods we consider two low pass filters with cut off frequencies of 450Hz and 1150Hz and Brownian noise. As a newer method we investigate a filter for spectro-temporal frequencies. To evaluate each method, appropriately processed recordings were presented to a group of participants in a perceptual experiment. The intelligibility was measured by means of the Levenshtein distance. Our results show that erosion itself performs similarly to the established methods, while a combination of erosion and low-pass filter outperforms all other methods.}, language = {en} } @inproceedings{WallravenCunninghamFleming, author = {Wallraven, Christian and Cunningham, Douglas William and Fleming, R.

In recent years many perspective SFS models have been studied that yield useful SFS approaches when a photographed object is close to the camera. However, while the ambiguities inherent to the classical, orthographic SFS models are well-understood, there has been no discussion of possible ambiguities in perspective SFS models. In this paper we deal with the latter issue. Therefore we adopt a typical perspective SFS setting. We show how to transform the corresponding image irradiance equation into the format of the classical orthographic setting by employing spherical coordinates. In the latter setting we construct a convex-concave ambiguity for perspective SFS. It is to our knowledge the first time in the literature that this type of ambiguity is constructed and verified for a perspective SFS model.}, language = {en} } @inproceedings{HahnCastilloCunningham, author = {Hahn, Philipp and Castillo, Susana and Cunningham, Douglas William}, title = {Look Me in the Lines: The Impact of Stylization on the Recognition of Expressions and Perceived Personality}, series = {IVA '18, Proceedings of the 18th International Conference on Intelligent Virtual Agents, Sydney, NSW, Australia, November 05-08, 2018}, booktitle = {IVA '18, Proceedings of the 18th International Conference on Intelligent Virtual Agents, Sydney, NSW, Australia, November 05-08, 2018}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-4503-6013-5}, doi = {10.1145/3267851.3267881}, pages = {339 -- 340}, language = {en} } @inproceedings{CastilloHahnLegdeetal., author = {Castillo, Susana and Hahn, Philipp and Legde, Katharina and Cunningham, Douglas William}, title = {Personality Analysis of Embodied Conversational Agents}, series = {IVA '18 Proceedings of the 18th International Conference on Intelligent Virtual Agents, Sydney, NSW, Australia, November 05-08, 2018}, booktitle = {IVA '18 Proceedings of the 18th International Conference on Intelligent Virtual Agents, Sydney, NSW, Australia, November 05-08, 2018}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-4503-6013-5}, doi = {10.1145/3267851.3267853}, pages = {227 -- 232}, language = {en} } @inproceedings{CunninghamAshkerov, author = {Cunningham, Douglas William and Ashkerov, Mikhail}, title = {Using a spatiotemporal plane to recover a moving object's shape using Spatiotemporal Boundary Formation}, series = {WSCG 2018, Plzen, Czech Republic, May 28-June 1, 2018, Poster proceedings}, booktitle = {WSCG 2018, Plzen, Czech Republic, May 28-June 1, 2018, Poster proceedings}, publisher = {University of West Bohemia}, address = {Pilsen}, isbn = {978-80-86943-42-8}, doi = {10.24132/CSRN.2018.2803.9}, pages = {61 -- 66}, language = {en} } @inproceedings{LegdeCastilloCunningham, author = {Legde, Katharina and Castillo, Susana and Cunningham, Douglas William}, title = {AgeRegression: Rejuvenating 3D-Facial Scans}, series = {WSCG 2018, Plzen, Czech Republic, May 28-June 1, 2018, Short Papers Proceedings}, booktitle = {WSCG 2018, Plzen, Czech Republic, May 28-June 1, 2018, Short Papers Proceedings}, publisher = {University of West Bohemia}, address = {Pilsen}, isbn = {978-80-86943-41-1}, doi = {10.24132/CSRN.2018.2802.24}, pages = {190 -- 199}, language = {en} } @inproceedings{KoulierisDrettakisCunninghametal., author = {Koulieris, George Alex and Drettakis, George and Cunningham, Douglas William and Mania, Katerina}, title = {Gaze prediction using machine learning for dynamic stereo manipulation in games}, series = {2016 IEEE Virtual Reality (VR, 19-23 March 2016, Greenville, SC, USA}, booktitle = {2016 IEEE Virtual Reality (VR, 19-23 March 2016, Greenville, SC, USA}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-5090-0836-0}, doi = {10.1109/VR.2016.7504694}, pages = {8}, language = {en} } @inproceedings{GutheSchardtGoeseleetal., author = {Guthe, Stefan and Schardt, P. and Goesele, M. and Cunningham, Douglas William}, title = {Ghosting and popping detection for imagebased rendering}, series = {3DTV-Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON), Hamburg, Germany}, booktitle = {3DTV-Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON), Hamburg, Germany}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-5090-3313-3}, doi = {10.1109/3DTV.2016.7548891}, pages = {4}, language = {en} } @misc{FotsingTchuitcheuBesongetal., author = {Fotsing, Cedrique and Tchuitcheu, Willy Carlos and Besong, Lemopi Isidore and Cunningham, Douglas William and Bobda, Christophe}, title = {A specialized pipeline for efficient and reliable 3D semantic model reconstruction of buildings from indoor point clouds}, series = {Journal of Imaging}, volume = {10}, journal = {Journal of Imaging}, number = {10}, editor = {Mei, Guofeng}, publisher = {MDPI}, issn = {2313-433X}, doi = {10.3390/jimaging10100261}, abstract = {Recent advances in laser scanning systems have enabled the acquisition of 3D point cloud representations of scenes, revolutionizing the fields of Architecture, Engineering, and Construction (AEC). This paper presents a novel pipeline for the automatic generation of 3D semantic models of multi-level buildings from indoor point clouds. The architectural components are extracted hierarchically. After segmenting the point clouds into potential building floors, a wall detection process is performed on each floor segment. Then, room, ground, and ceiling extraction are conducted using the walls 2D constellation obtained from the projection of the walls onto the ground plan. The identification of the openings in the walls is performed using a deep learning-based classifier that separates doors and windows from non-consistent holes. Based on the geometric and semantic information from previously detected elements, the final model is generated in IFC format. The effectiveness and reliability of the proposed pipeline are demonstrated through extensive experiments and visual inspections. The results reveal high precision and recall values in the extraction of architectural elements, ensuring the fidelity of the generated models. In addition, the pipeline's efficiency and accuracy offer valuable contributions to future advancements in point cloud processing.}, language = {en} } @article{WallravenFischerCunninghametal., author = {Wallraven, Christian and Fischer, J. and Cunningham, Douglas William and Bartz, Dirk and B{\"u}lthoff, Heinrich H.}, title = {The Evaluation of Real-World and Computer-Generated Stylized Facial Expressions}, language = {en} } @article{SchwaningerWallravenCunninghametal., author = {Schwaninger, Adrian and Wallraven, Christian and Cunningham, Douglas William and Chiller-Glaus, Sarah D.}, title = {Processing of identity and emotion in faces: a psychophysical, physiological and computational perspective}, series = {Progress in Brain Research}, volume = {156}, journal = {Progress in Brain Research}, issn = {1875-7855}, pages = {321 -- 343}, language = {en} } @article{RieckeCunninghamBuelthoff, author = {Riecke, B.
