Abstract (en)
[origin: WO2015104585A1] The invention relates to a method to construct a descriptor from binary silhouette images. The input image is a black-and-white (binary) image including the silhouette (a complete closed region of white pixels) of an object (i.e. a target) in front of a complete black background. The method calculates curvatures for both the Gaussian Scale-space and the morphological scale-space of the curve. Then these planar orientations are mapped to a color image, in order to describe the silhouette object. This descriptor can be used for object recognition purposes.
