In image processing, histogram matching or histogram specification is the transformation of an image so that its histogram matches a specified histogram. The well-known histogram equalization method is a special case in which the specified histogram is uniformly distributed. It is possible to use … Visa mer Consider a grayscale input image X. It has a probability density function pr(r), where r is a grayscale value, and pr(r) is the probability of that value. This probability can easily be computed from the histogram of the … Visa mer In typical real-world applications, with 8-bit pixel values (discrete values in range [0, 255]), histogram matching can only approximate the … Visa mer • Histogram equalization • Image histogram • Color mapping Visa mer The following input grayscale image is to be changed to match the reference histogram. The input image has … Visa mer The histogram matching algorithm can be extended to find a monotonic mapping between two sets of histograms. Given two sets of histograms Visa mer WebbExtending the dynamic range can present much richer contrasts and physical information from the traditional low dynamic range (LDR) images. To tackle this, we propose a …
