Curvature Estimation in Orientation Selection
Abstract
To summarize, progress has been made on a family of related problems, including: A model of endstopped visual cortical neurons was extended to include complex components; An extensive simulation of the model was completed with regard to orientation, positional, spatial frequency, curvature, chevron, and end-line sensitivity; Orientation discontinuities were extended into the motion domain, and psychological and computational experiments were performed to confirm the hypothesis of multiple directions being represented at a point of discontinuity; A theory was developed to capture the non-linearities necessary for early measurement of orientation and curvature; A totally different theory has begun to take shape for functionally characterizing cytochrome oxidase blobs; and The mathematical foundations were laid for a theory of shape.
