Abstract
An image processing method, implemented in a calculator, includes applying a process by group of pixels to an original image. For each group of pixels, calculating a cumulative sum of value or position differences of the pixels of the group of pixels, and for each group of pixels, allocating in a final image signal a pixel position of the group of pixels to each pixel value of the group of pixels so as to minimize the cumulative sum of differences calculated for the group of pixels according to the differences calculated. For each group of pixels, determining a filtering intensity according to the cumulative sum of differences calculated for the group of pixels, and applying to the group of pixels a filtering having the filtering intensity.
