METHOD FOR DESCRIBING PLANAR CURVES USING MORPHOLOGICAL SCALE SPACES

摘要

The present invention relates to a method of building a binary descriptor from the silhouette image. The input image is a (binary) image that contains black and white silhouette (completely closed area of ​​white pixels) of the object (ie, the target (target)) in front of a full black background. The method form of the curve significant scale-calculates the curvature of both space-space and Gaussian scale. Then these planar direction are mapped to the color image to describe the object silhouette. This descriptor can be used for object recognition purposes. ;
