ImageLines returns a list of line segments where the are expressed in the standard image coordinates .
ImageLines finds lines in the image whose normalized strength is larger than the specified threshold t.
In ImageLines, the parameter d controls how close lines are suppressed. If the value is set to zero, all detected lines are returned. With d set to , only the strongest line may be returned.
By default, ImageLines computes lines based on the Hough transform of the image, using the setting Method.
Lines are detected by iteratively selecting the strongest peaks in the Hough transform. Using the distinctness parameter, peaks that are within a rectangular range from the already selected peaks are excluded from the set of line candidates.
With Method, lines are detected using random sampling. For each sampling, pixels that are within a distance specified by the distinctness parameter d are used for computing the strength of the line. The pixels on the selected line are not used in the following iterations.
By default, ImageLines returns lines that span from border to border. With a setting True, detected lines may be divided into smaller segments.
