Abstract:
Small vibration of eye ball, which occurs when we fix our gaze on object, is called ``fixational eye movement.'' It has been reported that this function works also as a clue to monocular depth perception. Moreover, researches for a depth recovery method using camera motions based on an analogy of fixational eye movement are in progress. We suppose that depth perception with fixational eye movement is firstly carried out, and subsequently such depth information is supplementary used for binocular stereopsis. Especially in this study, using camera motions corresponding to the smallest type of fixational eye movement called ``tremor,'' we construct depth perception algorithm which models camera motion as a irregular perturbation, and confirm its effectiveness.
