Abstract

R, with the proper packages installed, provides a powerful platform for image manipulation and feature extraction. Strengths and weaknesses of three techniques for extracting characteristics from images containing a rectangular grid (with and without defects) are contrasted. Techniques discussed are the 2 dimensional fast Fourier transform (FFT), the Hough transformation for line detection, and topological data analysis (TDA) utilizing Vietoris-Rips persistence barcodes.
