Interface ImageHessian<Output extends ImageSingleBand>

All Superinterfaces:

ImageDerivative<Output,Output>

All Known Implementing Classes:

ImageHessian_Reflection

public interface ImageHessian<Output extends ImageSingleBand>
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.
