A steganalytic algorithm for 3D polygonal meshes (2014)
Presentation / Conference Contribution
Yang, Y., Pintus, R., Rushmeier, H., & Ivrissimtzis, I. (2014, October). A steganalytic algorithm for 3D polygonal meshes. Presented at 2014 IEEE International Conference on Image Processing (ICIP), Paris, France

We propose a steganalytic algorithm for watermarks embedded by Cho et al.'s mean-based algorithm [1]. The main observation is that while in a clean model the means of Cho et al.'s normalized histogram bins are expected to follow a Gaussian distributi...

The gradual emergence of spatially selective target processing in visual search: From feature-specific to object-based attentional control (2014)
Journal Article
Eimer, M., & Grubert, A. (2014). The gradual emergence of spatially selective target processing in visual search: From feature-specific to object-based attentional control. Journal of Experimental Psychology: Human Perception and Performance, 40(5), 1819-1831. https://doi.org/10.1037/a0037387

To dissociate feature-based and object-based stages in the control of spatial attention during visual search, we employed the N2pc component as an electrophysiological marker of attentional object selection. Participants searched for a target object...

Perceptual estimates can be biased by previously seen stimuli in delayed estimation tasks. These biases are often toward the mean of the whole stimulus set. Recently, we demonstrated such a central tendency bias in delayed color estimation. In the Ba...

Improved Depth Recovery In Consumer Depth Cameras via Disparity Space Fusion within Cross-spectral Stereo (2014)
Presentation / Conference Contribution
Payen de La Garanderie, G., & Breckon, T. (2014, September). Improved Depth Recovery In Consumer Depth Cameras via Disparity Space Fusion within Cross-spectral Stereo. Presented at Proceedings of the British Machine Vision Conference

We address the issue of improving depth coverage in consumer depth cameras based on the combined use of cross-spectral stereo and near infra-red structured light sensing. Specifically we show that fusion of disparity over these modalities, within the...

How the distorted representation of visual space in our brain constrains the way we move our eyes. (2014)
Presentation / Conference Contribution
(2014). How the distorted representation of visual space in our brain constrains the way we move our eyes. https://doi.org/10.1167/14.10.751

The representation of visual space is distorted in several areas of the brain, including the Superior Colliculus (SC) where population averaging presumably determines the amplitude of saccadic eye movements. We previously showed, based on human behav... Read More about How the distorted representation of visual space in our brain constrains the way we move our eyes..

Models of saccade programming in the superior colliculus (SC) have been limited in what inputs they can accept, typically isolated coordinates in visual space (e.g., Ottes et al., 1986, Vision Research [1]). We addressed this problem by integrating [... Read More about An image-based population model of human saccade programming in the Superior Colliculus.
