More Information
Summary:An image processing method includes dividing an image into one or more regions, obtaining a region-based histogram smoothing function for processing the image to have a uniform number of pixels based on a pixel value for each of the divided region, obtaining a global smoothing function for an entire image using the obtained region-based histogram smoothing function, obtaining a local smoothing function for each pixel of the image using the region-based histogram smoothing function applied to a region in a block, and obtaining a sum of weight values of the global smoothing function and the local smoothing function, and determining the pixel value, based on the obtained sum of the weight values.
