Hey all,
I have few questions about FREAK implementation in opencv I really need to know to continue:
1. I cannot get what the 64 values (columns) returned for each keypoint ? FREAK should return binary values as I understand?
2. I used BruteForceMatcher<Hamming> like in FREAK_demo.cpp in opencv samples. however it always give matches that may be wrong .. so I want to filter result ... I want to use the distance variable in the DMatch object returned but I cannot get what it representing in case of Hamming distance?.. should I take the big distances or small ?? what is the expected range for it ? I cannot find in any documentation
I hope someone can help
Thank you in advance
