org.openimaj.tools.vis.QuantisedSIFTPatchExtractor

public class QuantisedSIFTPatchExtractor
extends Object

Tool to extract prototypical quantised SIFT patches from a set of images and their corresponding quantised SIFT features. Patches are extracted by blurring the image to the correct scale and then extracting the patch using its geometry. It is assumed that the patch size is 2 * 2 * 3 * scale as per the original geometry suggested in Lowe's SIFT paper.
