Abstract: On the traditional foundation of characteristic image method,this paper proposes a kind of mobile examination algorithim based on the piecemeal edge characteristic image.This method carries on piecemeal processing to the background chart and the stacking chart,separately takes out their biggest characteristic vector,obtains each block projection coefficient,carries on the match examination of the mobile.In actual practice,the canny operator is used to obtain the edge detection so as to eliminate...
