What do you mean? The Laplacian is a high pass filter. What do you want to segment? Where did you upload your image? Have you tried imfilter() or conv2() to perform the Laplacian filter?

Regarding your "Answer" ... How do you want to segment it? Will thresholding to the job?

edgeImage = filteredImage > 5;

i used conv2 for the filter.i actually use an adaptive laplacian kernel that preserves edges.Now with the aid of this adative kernel i need to perform image segmentation.
