改进的二维OTSU算法,基于梯度和灰度值的变换-improved 2D OTSU method.

基于邻域灰度梯度的改进二维OTSU算法：在二维OTSU的方法上进行改进，将纵坐标改用像素点的灰度值与其邻域的平均灰度值的差的绝对值，分割图像。-Neighborhood-based two-dimensional gray-scale gradient improved OTSU algorithm: to improve on the two-dimensional OTSU method, the vertical axis instead of the absolute value of
