Shape proportion and encircled image-histogram code. Requires code from "Image Operators: Image Processing in Python" by Dr. Jason M. Kinser. Specifically, it needs mgcreate's Plop function.
Provides the main functions to perform SPEI. Also has supporting functions to perform SPEIs of images in in multiple directories.
Example of performing SPEI on square image.
Example of how to perform SPEI on group of images in a directory. May need to be changed for given problem. For example, if user does not want to use Otsu thresholdingas a preprocessing step, other functions will need to be changed to accomodate this.
