Segmentation of handwritten signature images using the statistics of directional data
Robert Sabourin, Réjean Plamondon · 2003
A preliminary design is given for a general image-understanding system for the extraction of a signature representation. A novel version of an algorithm for centroidal-linkage region-growing with merging, using the statistics of directional data is given. It permits the extraction of textured regions characterized by local uniformity in the orientation of the gradient.>
