I have to track an object using LKoptical flow for that I require a set of good features in the specified region. Here in the forum I got example how to use LK and I also used the same in C++. But my question is, in C++ opencv I used a function called setROI for the image to find out the good features in the particular region. But If I use corner detection instead of good feature detection here in FastCV, I have to use it for whole image instead of specific region in the given image. Please will anyone tell me is that functionality available in fastcv? If it is will u tell me which api it is?. If thats not possible can anyone suggest me to use anyof the other ways to get the things done.
Thanks in advance,
