SYNTAX

[edge_mag, edge_dir] = kirsch_ed_cvip(input_image)

Input Parameter include:

input_image - Input image can be gray image or rgb image of MxN size.

Output Parameters include:

edge_mag - The magnitude of the edges. An image with the same size as the input image.

edge_dir - The direction of the edges. An image with the same size as the input image.

DESCRIPTION

This function performs the Kirsch edge detection operation on an input image. The function has two outputs i.e., The edge Magnitude and edge direction. The eight compass masks of the Kirsch edge detector are convolved with each band of the input image.
