dcv.tracking.opticalflow.pyramidflow

Module contains optical flow pyramid implementation.

Pyramidal optical flow evaluation in $(BIG DCV) is designed to be a wrapper to actual optical flow algorithm. Sparse and dense optical flow algorithms have a corresponding utility class which will evaluate the algorithm in $(LINK3 https://en.wikipedia.org/wiki/Pyramid_(image_processing)#Gaussian_pyramid, pyramid), coarse-to-fine fashion.

// Evaluate Horn-Schunck method in pyramid.
HornSchunckFlow hsFlow = new HornSchunckFlow(props);
DensePyramidFlow densePyramid = new DensePyramidFlow(hsFlow, pyramidLevels); 

auto flow = densePyramid.evaluate(current, next);
