WebFeb 27, 2011 · It all really depends on what you need though. If you just want "sphericity", I would give the voxel faces method a try. Once a method is developed you can figure out what it returns as a "sphericity" for various objects and correlate that to your data. WebBW = imbinarize (I) creates a binary image from 2-D or 3-D grayscale image I by replacing all values above a globally determined threshold with 1 s and setting all other values to 0 s. By default, imbinarize uses Otsu's method, which chooses the threshold value to minimize the intraclass variance of the thresholded black and white pixels [1 ...
