Biol gicas, Universidade Santa rsula. A Program to Compute Shape Coordinates, Uniform X and Y, and Centroid Size. Shape is a program to compute Bookstein's Shape Coordinates from 2-dimensional coordinates from a digitizer, TV etc. Shape coordinates are computed by rotating and translating individual landmark configurations to a baseline, and scaling them by the length of the baseline. The transformed coordinates of the other landmarks serve as variables that represent the shape of each specimen relative to this absolute reference orientation.
