Hi,
I am using GoodFeaturesToTrackDetector to extract features and then sort its results to pick the strongest of all. However responses (i.e. the corresponding KeyPoint.response value) are always zero. Whereas, thankfully I don't have the same problem with FASTDetector. Do you have any ideas, solutions?
My OpenCV version (as I copied from Synaptic) is 2.4.8+dfsg1-2ubuntu1. It is the default version comes with Ubuntu 14.04.
Thanks
