A RANDOMIZED HOUGH TRANSFORM USING GRADIENT DIRECTION INFORMATION

To solve the problem of a large amount of useless accumulations yielde d by random sampling by means of the randomized Hough transform (RHT)i n handling complex images, an improved RHT used to detect lines was pr oposed. It uses gradient direction information, not only can well solv e the problem of useless accumulations, but also has higher speed, sma ller storage and better detection performance.
