Class SparseIntegralGradient_NoBorder<T extends ImageSingleBand,G extends GradientValue>

java.lang.Object

boofcv.struct.sparse.SparseScaleGradient<T,G>

boofcv.alg.transform.ii.SparseIntegralGradient_NoBorder<T,G>

All Implemented Interfaces:

SparseImageGradient<T,G>, SparseImageOperator<T>

Direct Known Subclasses:

SparseIntegralGradient_NoBorder_F32, SparseIntegralGradient_NoBorder_I32, SparseIntegralHaar_NoBorder_F32, SparseIntegralHaar_NoBorder_I32

public abstract class SparseIntegralGradient_NoBorder<T extends ImageSingleBand,G extends GradientValue>
extends SparseScaleGradient<T,G>

Computes the gradient from an integral image. Does not check for border conditions. Much faster than generalized algorithms that can handle image borders, but is unsafe and bounds must be checked before use.
