Class GenericHoughDetection<S>

java.lang.Object

org.area515.resinprinter.inkdetection.visual.GenericHoughDetection<S>

public class GenericHoughDetection<S>
extends java.lang.Object

This class is the Hough Transform Space and search for generic objects in a binary image. The image must have been passed through an edge detection module and have edges marked in white (background must be in black). This code is loosely based off of Hemerson Pistori (pistori@ec.ucdb.br) Hough Circle Detection code. I made it generic to allow the detection of arbitrary shapes.
