The conventional Hough transform can only count the number of feature points which are collinear, and can't record the end points of a line segment and its length. Thereby, this paper present an improved Hough transform to overcome these two shortcomings. The algorithm is parallelized and implemented in MCC. What's more, we give a parallel algorithm to identify and eliminate overlapping line segments. These advantages are very useful in the real applications.
