CornerFilter

CornerFilter[image]
computes a measure for the presence of a corner for each pixel in image and returns the result as an intensity image.

detects corners at a pixel range r.

CornerFilter implements a variety of corner detection methods based on gradient computations.

When applied to multichannel images, CornerFilter finds corner signatures across channels.

CornerFilter takes a Method option that specifies how to compute the corner metric. The default setting is . Available methods include:

	"HarmonicMean"	harmonic mean of eigenvalues method
	"HarrisStephens"	Harris-Stephens corner detection
	{"HarrisStephens",k}	Harris-Stephens method with sensitivity parameter k
	"ShiTomasi"	minimum eigenvalue method

The parameters of the Gaussian derivatives to be computed can be specified by an option setting . The default setting is .
