MATLAB implementation to identify the image of the
4.0
Hough transform is a vote on the principle of using a parameter estimation techniques. The principle is the point of the image space using the Hough parameter space and the line - duality, to convert the image space to the parameter space of the detection problem. By simple statistics accumulated in the parameter space, and then in the Hough parameter space to find a method of detecting the peak value of the accumulator line. The first image preprocessing procedures, using the Hough transform to extract the clock hour hand, minute hand, second hand, and then calculating the hour, minute angle is calculated based on their angle of their points of time, the image file has three test by.
