\subsection{Histogram Based Methods}  Histogram based methods (as the name implies) computes for the histogram of the image and cluster the values around the significant peaks. It relies on the tendency of images to have a bimodal or multi-modal histogram due to the contrast between the background and the foreground. Histogram based methods are relatively fast because it only needs to read the pixel values once. However, it does not work well with low contrast images because there may not be any clear or significant peaks.
