Hough transform this program. Hough transform image processing image recognition from the basic geometry methods. The basic principle of Hough transform is to use point and line duality, the original image space curve given expression through the curve of the parameter space into a point. This had given the original image in the detection curve into a parameter space to find the problem in the peak. That is, the overall characteristics of the detection of local features into testing. For example, a straight line, oval, round, arc and so on.
