Removed Snap! button and Process tab from the notebook. Changed image display from label to a separate window, in order to have better frame rate. The camera requests only the depth image. After clicking on Start Video, the depth image is displayed continuously. Every 1 second a process of finger detection is started on a different core. After finishing the calculation the bounding box of the hand and the number of detected fingers is updated. Signed-off-by: Daniel Matyas <[email protected]>
First of all, it is faster, because there is no GUI, only computation. Used depth image directly for computation; did not convert image to RGB. Made max distance of the bit image dynamic. It depends on the closest pixel. Changed hand center to the point farthest from the background Made cdist_threshold dynamic. It is inversely proportional to the max distance of bit image. Selected the vertex which is farthest from the hand center on every finger. Neglected the vertices which are below the wrist. Signed-off-by: Daniel Matyas <[email protected]>
