Uncertainty in visual processes predicts geometrical optical illusionsCornelia Fermuller
Department of Computer Science, Computer Vision Laboratory, Center for Automation Research, Institute for Advanced Computer Studies, University of Maryland, College Park, MD 20742 3275, USA
Vision Res 44:727-49. 2004..Thus, the broader message of this paper is that there is a general uncertainty principle which governs the workings of vision systems, and optical illusions are an artifact of this principle...
Illusory motion due to causal time filteringCornelia Fermuller
Computer Vision Laboratory, Center for Automation Research, Institute for Advanced Computer Studies, University of Maryland, College Park, MD 20742 3275, United States
Vision Res 50:315-29. 2010..In an experiment the perception of the different illusory signals was quantitatively compared by nulling the illusory motion with opposing real motion, and was found to be predicted well by the model...
Motion segmentation using occlusionsAbhijit S Ogale
Center for Automation Research, Department of Computer Science, University of Maryland, College Park, MD 20742, USA
IEEE Trans Pattern Anal Mach Intell 27:988-92. 2005..Finally, we describe another category of moving objects which is detected using cardinal comparisons between structure from motion and structure estimates from another source (e.g., stereo)...
Depth estimation using the compound eye of dipteran fliesKonstantinos Bitsakos
Computer Vision Laboratory, UMIACS, University of Maryland, College Park, MD, USA
Biol Cybern 95:487-501. 2006..Our results indicate that depth estimation at small distances (up to about 1.5-2 cm) is reasonably accurate. This would allow the insect to obtain at least an ordinal spatial layout of its operational space when walking...
A 3D shape constraint on videoHui Ji
Center for Automation Research, University of Maryland, College Park, MD 20742 3275, USA
IEEE Trans Pattern Anal Mach Intell 28:1018-23. 2006..Experiments demonstrate its usefulness as a tool in structure from motion providing very accurate estimates of 3D motion...
Noise causes slant underestimation in stereo and motionHui Ji
Computer Vision Laboratory, Center for Automation Research, Institute for Advanced Computer Studies, University of Maryland, College Park, MD 20742-3275, USA
Vision Res 46:3105-20. 2006..For the case of 3D motion we demonstrate the bias by means of a new illusory display. Finally, we discuss statistically optimal strategies for the problem and suggest possible avenues for visual systems to deal with the bias...
