Description copied from interface: GeneralFeatureIntensity

Computes the corner's intensity. Before computing the various image derivatives call GeneralFeatureIntensity.getRequiresGradient() and GeneralFeatureIntensity.getRequiresHessian() to see if they are needed.

Parameters:

input - Original input image

derivX - First derivative x-axis

derivY - First derivative x-axis

derivXX - Second derivative x-axis x-axis

derivYY - Second derivative x-axis y-axis

derivXY - Second derivative x-axis y-axis
