Moment preserving detection of elliptical shapes in gray-scale images

A new method for elliptical shape detection based on the principle of gray and mass moment preserving is proposed. For each elliptical region in a gray-scale image, automatic bilevel thresholding based on gray moment preserving is used first to transform the blurred image in the region into a binary...
