Edge Detection Consider this picture We would like its output to be So to repeat The purpose of Edge Detection is to find jumps in the brightness function of an image and mark them Before we get into details we need to detour.

This project focuses on the use of Radial Basis Functions in Edge Detection in both one-dimensional and two-dimensional images. We will be using a 2-D iterative RBF edge detection method. We will be varying the point distribution and shape parameter. We also quantify the effects of the accuracy of the edge detection on 2-D images. Furthermore, we study a variety of Radial Basis Functions and their accuracy in Edge Detection. . Outline. Contour drawing in art. S. il. h. o. uette. . / outline. Definition of outlines.
