Contents

SYNTAX

I_MD  = moravec_corner_cvip( I , e)

Input Parameters include:

Output Parameter Include :

DESCRIPTION

Moravec Filter is the simplest corner detector. This is used to find the points of maximum contrast ,which corresponds to potential corners and sharp edges. It finds the average difference between a pixel and its neighbors in all directions. Then the threshold operation is applied on the image.
