A new method is proposed here termed weighted Hough transform (WHT). The advantage of the WHT is that it can be applied to the differential image directly without the need for thresholding. In the WHT the contribution of each pixel to the parameter domain is weighted according to its value. It is well known that the performance of the conventional Hough transform is dependent on the threshold value used. The new method is therefore a generalizing of the Hough transform to overcome this problems.
