public interface ImageHessian<Output extends ImageGray<Output>> extends ImageDerivative<Output,Output>
A generic interface for computing image's second derivatives given the image's gradient. This is typically faster than computing the Hessian directly.
processvoid process(Output inputDerivX, Output inputDerivY, Output derivXX, Output derivYY, Output derivXY)Computes all the second derivative terms in the image.
inputDerivX- Precomputed image X-derivative.
inputDerivY- Precomputed image Y-derivative.
derivXX- Second derivative x-axis x-axis
derivYY- Second derivative y-axis y-axis
derivXY- Second derivative x-axis y-axis
