Class DenseOpticalFlowKlt<I extends ImageGray,D extends ImageGray>

java.lang.Object

boofcv.alg.flow.DenseOpticalFlowKlt<I,D>

public class DenseOpticalFlowKlt<I extends ImageGray,D extends ImageGray>
extends java.lang.Object

Computes the dense optical flow using KltTracker. A feature is computed from each pixel in the prev image and it is tracked into the curr image. The flow assigned to a pixel is the template with the lowest error which overlaps it. In other words, a pixel is assigned the flow with the lowest error with in 'radius' pixels of it. A pixel is marked as invalid if all tracks around the pixel fail.
