Edge Detection in an Image by Using the Elimination Rule

Edges are significant local changes of intensity in an image. In this paper, an elimination rule which based on triangular inequality elimination (TIE) has been adopted to perform the edge detection procedures. A new method has been included the combining between an elimination rule which based on triangular inequality elimination (TIE) and the differentiation operator by using the filters mask in one dimension. The introduced algorithm has been produced a good image quality by comparison with that which may be obtained by using the differentiation operator of sharpening an image. The proposed algorithm has been proved it is good for finding the edge in an image data
