Image processing method for detail enhancement and noise reduction

An image processing method for detail enhancement and noise reduction, the method comprising:

• calculating an information measure derived from original image information, in which the information measure is a spread measure or an entropy measure;
• calculating a weighting measure based, at least in part, on the information measure derived from the original image information, wherein the weighting measure is greater than zero and is calculated on the basis of scaling with a constant with the calculated information measure as input data;
• applying a low-pass filter to an original image to form a low-pass filtered image;
• calculating an uncompressed high-pass filtered image by subtracting the low-pass filtered image from the original image;
• scaling the uncompressed high-pass filtered image with the weighting measure;
• compressing the low-pass filtered image;
• and
• obtaining a detail-enhanced and noise-reduced image by adding the uncompressed high-pass filtered image scaled with the weighting measure to the compressed low-pass filtered image.
