Package boofcv.abst.filter.convolve

Class GenericConvolveDown<Input extends ImageBase<Input>,Output extends ImageBase<Output>>

java.lang.Object

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

All Implemented Interfaces:

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

public class GenericConvolveDown<Input extends ImageBase<Input>,Output extends ImageBase<Output>>
extends Object
implements ConvolveDown<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).
