Abstract
The performance of the "Fusion" mechanism for application in stereo analysis of range was investigated in an earlier paper [1]. This method restricted the depth of field and therefore required a shift variant mechanism in the peripheral area to find disparity. Mis-registration was prevented by restricting the disparity detection range to a neighborhood spanned by the directional edge detection filters. This transformation was essentially accomplished by a non-uniform resampling of the original image in a horizontal direction. While this is easily imple-mented for digital processing this approach does not (in the peripheral vision area) model the log-conformal mapping which is known to occur in the human mechanism. This paper therefore modifies the original fusion concept in the peripheral area to include the polar exponential grid-to-log conformal tesselation. Examples of the fusion process resulting in accurate disparity values are given.
