Zero response from GoodFeaturesToTrackDetector

asked 2015-02-15 03:49:34 -0600


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.

I had the exact same problem. Was writing a feature detection comparison algorithm and left out the GoodFeaturesToTrack since it didnt yield a single feature, whereas the others did (except for the blob one in this case). Curious what could be the reason, up for some deeper investigation in this?
