Hough transform for lines Input: img - 2D binary image with nonzeros representing edges angle_step - Spacing between angles to use every n-th angle between -90 and 90 degrees. Default step is 1. lines_are_white - boolean indicating whether lines to be detected are white value_threshold - Pixel values above or below the value_threshold are edges Returns: accumulator - 2D array of the hough transform accumulator theta - array of angles used in computation, in radians. rhos - array of rho values. Max size is 2 times the diagonal distance of the input image. |
