Which algorithm is used for edge detection?

Common edge detection algorithms include Sobel, Canny, Prewitt, Roberts, and fuzzy logic methods. Image segmentation using the Sobel method. Image segmentation using the Canny method.

What algorithm is used to detect the lines?

Thus, the Hough Transform algorithm detects lines by finding the (ρ, θ) pairs that have a number of intersections larger than a certain threshold.

What is edge detection and line detection?

Edge detection is the process of finding outlines in an image, whatever they look like. Line detection finds line segments (sometimes by extension, other geometric figures such as circular arcs).

Which method is best for detection of lines?

EDLines, LSD and Hough Transform are the best line detection methods that are known in the literature.
