Control algorithm of media player was proposed by dynamic hand gesture

using thinking in finite state automation.Firstly

sequences image was converted from RGB color space to YCrCb

in which gesture target region and its center were obtained by means of otsu.Secondly

center of target region and frame delay time were input signal of finite state automation

different functions of media player were its state

different gesture commands were decided by input signal and current state.Finally

functions of media player such as pause/continue、next/previous and volume adjustment were realized by windows system function keybd_event () .Experimental results show that media player can be controlled real-timely and effectively using the algorithm

Midas Touch program is perfectly solvable.
