skimage.feature.corner_kitchen_rosenfeld(image, mode='constant', cval=0) [source]

Compute Kitchen and Rosenfeld corner measure response image.

The corner measure is calculated as follows:

1 2	(imxx * imy**2 + imyy * imx**2 - 2 * imxy * imx * imy)     / (imx**2 + imy**2)

Where imx and imy are the first and imxx, imxy, imyy the second derivatives.

Parameters:	image : ndarray Input image. mode : {‘constant’, ‘reflect’, ‘wrap’, ‘nearest’, ‘mirror’}, optional How to handle values outside the image borders. cval : float, optional Used in conjunction with mode ‘constant’, the value outside the image boundaries.
Returns:	response : ndarray Kitchen and Rosenfeld response image.
