Full Body Detection with OpenCV & C++ -


i using opencv full body detection on ar.drone , wanted know settings/limits minsize , maxsize parameters? of have them blank, code seems detect people well. have minneighbors parameter set 7. each time run code 20% false positives. hope setting size parameters reduce amount of false positives. input or suggestions on other parameter settings in addition size parameters helpful

the size parameters, in case, scene dependent. have check results on several images/sequences , see distribution of sizes of both true positives , false positives. after observing range of values each category, can adjust minsize , maxsize.

most likely, come point still have false positives , false negatives. @ point, can decide threshold values considering more costly have; false positives, or false negatives.

another approach post-process results returned recogniser, , remove false positives based on other criteria.
