Class ImageDistortCache_SB<Input extends ImageGray,Output extends ImageGray>

java.lang.Object

boofcv.alg.distort.ImageDistortCache_SB<Input,Output>

All Implemented Interfaces:

ImageDistort<Input,Output>

Direct Known Subclasses:

ImplImageDistortCache_F32, ImplImageDistortCache_I16, ImplImageDistortCache_I8, ImplImageDistortCache_S32

public abstract class ImageDistortCache_SB<Input extends ImageGray,Output extends ImageGray>
extends java.lang.Object
implements ImageDistort<Input,Output>

Except for very simple functions, computing the per pixel distortion is an expensive operation. To overcome this problem the distortion is computed once and cached. Then when the image is distorted again the save results are simply recalled and not computed again.
