| Abstract(in English) | In this report, we propose a speeding up method of line detection by the local polar coordinates method (LPCM). Hough transform has been generally used for detecting lines in noisy images. LPCM can decrease the processing time of line detection, keeping the good properties of Hough transform. But the decreasing rate depends on position and quantity of the noise. In the proposed speeding up method, a narrow area called window is introduced around the local pole of LPCM. Using a new voting method in the window, we can effectively judge whether the local pole is true or not. From the experimental results, we understand that the proposed speeding up method has high performance and its processing time does not depend on position and quantity of the noise. |
