corner-moravec

corner_moravec

skimage.feature.corner_moravec()

Compute Moravec corner measure response image.

This is one of the simplest corner detectors and is comparatively fast but has several limitations (e.g. not rotation invariant).

Parameters:	image : ndarray Input image. window_size : int, optional (default 1) Window size.
Returns:	response : ndarray Moravec response image.
