Abstract
We describe how to vote in the parameter space of the Hough transform in a digital image. It has been proven that the calculation cost can be reduced by using the direction and length of the segments. However, the previous algorithm can not represent the value of the correct peaks in the parameter space because the parameter space was defined as a discrete intercept and slope interval. In this paper, we propose an algorithm that uses the association of the intercept and slope parameters and the length of the segments of the digital lines. We show by experimental results that the algorithm can detect the correct value of the peaks in the parameter space.
