An image can be sharpened by high pass filtering of its discrete Fourier transform or by an equivalent convolution … taken here to sharpening and edge detection, as well as smoothing and other processing is to use a ‘smart’ convolution mask … that makes rule-based decisions. Upon employing gains in the rule consequents, we achieve a type of fuzzy convolution of …
