Webimwrite(X,map,filename,fmt) writes the indexed image in X and its associated colormap map to filename in the format specified by fmt. If X is of class uint8 or uint16, imwrite writes the actual values in the array to the file. If X is of class double, the imwrite function offsets the values in the array before writing, using uint8(X-1). Webimwrite_png_compression 为对于png格式的图片,这个参数表示压缩级别(cv_imwrite_png_compression)从0到9。较高的值意味着更小的尺寸和更长的压缩时间,而默认值是3。 所以上述程序中选择了压缩级别为9。
