Anne Gelb: Region Extraction Using Edge Detection and B-Splines

This talk describes a method for region segmentation that combines a recently developed edge detection method, a novel point sequencing algorithm, and B-splines. The constructed edge map is rich with useful information that can be teased out for effective segmentation. By careful point sequencing that considers characteristic features of the underlying image, the resulting B-spline provides an accurate depiction of the regions of interest. The method is robust and computationally efficient, and would also be useful as an initialization step to active contour methods.
