c OpenCV and Unsharp Masking Like Adobe Photoshop ... 4th parameter is not "radius" it is "sigma" gaussian kernel standard deviation. Radius is rather "ksize". Anyway Photoshop is not open source, hence we can not be sure they use the same way as OpenCV to calculate radius from sigma. Channels. Yes you should apply sharp to any or to all channels, it depends on your purpose.
