The proposed method utilizes plateau limits to modify histogram of the image. In this method, histogram is divided into two sub- histograms on which histogram statistics are exploited to obtain the plateau limits. WebThe following steps must be performed in order to determine the histogram maxima: 1. Normalize the histogram (transform it into a PDF) 2. Choose a window width 2*WH+1(a good value for WH is 5) 3.
