Program to apply random elastic rubbersheet transforms to Netpbm color (.ppm, i.e., P6 raw color) images for augmenting training sets in machine learning/deep learning. The program reads an input .ppm image from stdin and writes a ppm image to stdout. Original Author: Marius Bulacu (.pgm version for characters). Adapted for .ppm and color: Lambert Schomaker.
