象棋识别

代码说明：

说明：  工作是棋盘图像二值化和棋子识别。针对棋盘全局二值化存在的问题,提出了基于相邻像素灰度差阈值的棋盘图像二值化方法。(The work is to binarize the chessboard image and recognize the chessboard. Aiming at the problem of global binarization of chessboard, a method of binarization of chessboard image based on gray difference threshold of adjacent pixels is proposed.)
