enhancement of image sharpness with bilateral and adaptive bilateral filter matlab codes

[dhanabhagya]

This preserves sharp edges by systematically looping through each pixel and adjusting weights to the adjacent pixels accordingly.
% bif = bilateral filter
% im = input image
% sigd = domain parameter for spatial kernel
% sigr = range parmeter for intensity kernel
% n = noise intensity
% out = output image
