gesture-recognition

install cmake, opencv2, run as below insturctions:

cmake .
make
./main

how to use

Gesture gesture(im);
// 存在手返回true, 否则false
gesture.HasHand();
// 返回的vector的大小为空，则没有手势匹配；1，匹配一字；2，匹配八字；
gesture.getFingerLocation(std::vector<cv::Point>)

step 1: find the hand

step 2: compared with template gestures by similarity

step 3: find the finger point by max convex

step 4: calculate convexity defects

step 5: keep the contours which depth > threshold, find the finger point

mkdir build
cmake -DCUDA_USE_STATIC_CUDA_RUNTIME=OFF ..
make
./main
