Hello,
I'm developing an Android app that requires object recognition. I built a PC desktop version where I use FREAK as a descriptor extractor and it provided very satisfying results. However, in my Android app, FREAK is incredibly slow. No matter which feature detector I use FREAK requires at least 6 seconds to extract. I find this very weird since ORB requires less than 1 second (also as a descriptor extractor) and BRIEF requires even less. Even SIFT and SURF as extractors are faster. I've seen topics here where people commented that FREAK speed was not as good as expected but nobody mentioned such huge difference in execution time. Is this normal or am I doing something wrong? If I am what could it be? Thank you
