Curvature Estimation in Orientation Selection
Abstract
This research effort is concentrated on the computational neuroscience of early vision. Progress was made on the following problems: (i) a model of end-stopped visual cortical neurons was extended to include complex components; (ii) an extensive simulation of the model was completed with regard to orientation, positional, spatial frequency, curvature, chevron, and end-line sensitivity; (iii) orientation discontinuities were extended into the motion domain, and psychophysical and computational experiments confirm the hypothesis of multiple directions being represented at a point of discontinuity; and (iv) the mathematical foundations were laid for a theory of shape. Several new projects were also initiated. Keywords: Neurophysiology; Spatial distribution.
