摘要

Chapter 8 presents a comprehensive study of methods used to identify geometric structures in digital images, focusing particularly on Hough Transform and its applications in detecting lines, circles, and other parametric shapes. It begins by explaining how gradient-based edge maps, obtained from previous filtering processes, can reveal structural elements that define objects within an image.
