自适应中值滤波函数，是根据被滤波区域的图像特性自适应的滤波器。-The adaptive median filtering function is based on the image characteristics of the filter region of the adaptive filter.

先在matlab上做一个数字滤波器，将b、a的值经过定点化以后移植到ccs中，在ccs中实现，并比较滤波效果！-To make a digital filter in matlab, first to b, a value through fixed-point after transplantation into the CCS, implementation in the CCS, and compare the filtering effect!

关于图像处理的色彩变换，中值滤波器,灰度变换等-About the image processing of color transformation, median filter, gray level transformation, etc
