The picture a histogram provides about the distribution of your process outcomes can help you determine what or where the problem might be. Why is histogram important in photography? WebbIn fact, Histogram equalization is also can be taken as histogram matching, since we modify the histogram of an input image to be similar to the normal distribution. In order to match the histogram of images A and B, we need to first equalize the histogram of both images. Then, we need to map each pixel of A to B using the equalized histograms. christopher cross concert dates

Through this adjustment, the intensities can be better distributed on the histogram utilizing the full range of intensities evenly. This allows for areas of lower local contrast to gain a higher contrast.
