Contours - USF
Chapter 6 Contours Edges must be linked into a representation for a region boundary. This representation is called a contour . The contour can be open or closed. Closed Contours correspond to region boundaries, and the pixels in the region may be found by a filling algorithm. An open contour may be part of a region boundary. Gaps can occur in a region boundary because the contrast between regions may not be enough to allow the edges along the boundary to be found by an edge detector. The edge detection threshold may have been set too high, or the contrast along some portion of the boundary may be so weak relative to other areas of the image that no single threshold works everywhere in the image.
The first section in this chapter presents the elementary differential geom etry of curves in the plane. The second section gives a collection of techniques
