1. An image processing method for detail enhancement and noise reduction, the method comprising: (a) creating an original image; (b) calculating, based on the original image, an information measure, in which the information measure is a spread measure, an edge detection measure or an entropy measure; (c) calculating a weighting measure on the basis of the information measure; (d) low-pass filtering the original image with a low-pass filter to form a low-pass filtered image, (e) calculating a high-pass filtered image by subtracting the low-pass filtered image from the original image; and (f) obtaining a detail-enhanced and noise-reduced image by adding the high-pass filtered image scaled with the weighting measure to the low-pass filtered image.
