Pmf to cdf
WebPMF and CDF are both use in histogram equalization as it is described in the beginning of this tutorial. In the histogram equalization, the first and the second step are PMF and CDF. Since in histogram equalization, we have to equalize all the pixel values of an image. So PMF helps us calculating the probability of each pixel value in an image.

WebGiven the joint pmf, we can now find the marginal pmf's. Note that the marginal pmf for \(X\) is found by computing sums of the columns in Table 1, and the marginal pmf for \(Y\) corresponds to the row sums. (Note that we found the pmf for \(X\) in Example 3.3.2 as well, it is a binomial random variable. We also found the pmf for \(Y\) in ...
