MATPLOTLIB IMAGE TUTORIAL — STAT 159/259 - GITHUB PAGES
Most often, the “interesting” part of the image is around the peak, and you can get extra contrast by clipping the regions above and/or below the peak. In our histogram, it looks like there’s not much useful information in the high end (not many white things in the image). Let’s adjust the upper limit, so that we effectively “zoom in on” part of the histogram. We do this by setting ...

B = imresize (A,scale) returns image B that is scale times the size of image A. The input image A can be a grayscale, RGB, binary, or categorical image. If A has more than two dimensions, then imresize only resizes the first two dimensions. If scale is between 0 and 1, then B is smaller than A. If scale is greater than 1, then B is larger than A.
