要約(英語): In image analysis, it is important to detect lines (straight lines) which represent edges of an object in the image. The most popular technique to detect lines is Hough Transform. In the transform, resulting peaks in the accumulator array which are gotten by a voting procedure in the parameter space represent strong evidence that a corresponding line exists in the image. In the voting procedure, a large number of votes which are far from the peaks are unnecessary and it makes the transform slow. In this paper, we propose a speed-up method by introducing a procedure in image space which removes lines except for the limited directional lines. Owing to the procedure, we can reduce voting range and remove the unnecessary vote. From the experimental results, we confirm that the proposed method has good performance.
