Class GenericConvolveDown<Input extends ImageSingleBand,Output extends ImageSingleBand>

java.lang.Object

boofcv.abst.filter.convolve.GenericConvolveDown<Input,Output>

All Implemented Interfaces:

ConvolveInterface<Input,Output>, FilterImageInterface<Input,Output>

public class GenericConvolveDown<Input extends ImageSingleBand,Output extends ImageSingleBand>
extends Object
implements ConvolveInterface<Input,Output>

Generalized interface for filtering images with convolution kernels while skipping pixels. Can invoke different techniques for handling image borders. The first pixel sampled is always (0,0) and the sampled pixels are (x*skip,y*skip).
