Histogram equalization to 255 preserves the non-zero-ness of the minimum value." The equalization formula for the example scaling data from 0 to 255, inclusive, is: For example, the cdf of 78 is 46. (The value of 78 is used in the bottom row of the 7th column.) The normalized value becomes Once this is done then the values of the equalized image are directly taken from the normalized cdf to yield the equalized values: Notice that the minimum value (52) is now 0 and the maximum value (154) is now 255. Histogram equalization Histogram equalization is a method in image processing of
