Resumo(s)
The primary visual cortex employs simple, complex and end-stopped cells to create a scale space of 1D singularities (lines and edges) and of 2D singularities (line and edge
junctions and crossings called keypoints). In this paper we show first results of a biological model which attributes information
of the local image structure to keypoints at all scales, ie junction type (L, T, +) and main line/edge orientations.
Keypoint annotation in combination with coarse to fine scale processing facilitates various processes, such as image matching (stereo and optical flow), object segregation
and object tracking.
