I have an OpenCV 2 C++ program which makes use of PyramidAdaptedFeatureDetector
(used over a GoodFeaturesToTrackDetector
for a Lukas-Kanade optical flow) and would like to port it to OpenCV 3. However I cannot find any trace of that class in the docs or in the code for OpenCV 3. Has it been removed? What is suggested as a replacement?
