A phantom surface is a stereoscopic illusory area that can be seen in depth although there is no conventional stereoscopic cues [Liu, L., Stevenson, S.B., & Schor, C.M. (1994). Quantitative stereoscopic depth without binocular correspondence. Nature, 367, 66-69; Gillam, B. & Nakayama, K. (1999). Quantitative depth for a phantom surface can be based on cyclopean occlusion cues alone. Vision Rese...

Many stereopsis algorithms attempt to recover depth over a wide range of disparities at every pixel location. If the disparity recovery process is limited to a smaller range of disparities, and if disparity measurements are only required where they can be extracted reliably, then the task of recovering `local' disparities can be simpli ed considerably. This paper presents an algorithm for extra...

Estimation of binocular disparity in vision systems is typically based on a matching pipeline and rectification. Estimation of disparity in the brain, in contrast, is widely assumed to be based on the comparison of local phase information from binocular receptive fields. The classic binocular energy model shows that this requires the presence of local quadrature pairs within the eye which show ...
