A good description is on this page.

Wikipedia also has its own Hough Transform article.

Pros

  • Able to detect dashed lines

Cons

  • Can only detect straight lines, making it almost useless for curved lines - which will probably be common
    • Useless for detecting curved lines
  • Designed to detect lines as opposed to detecting line segments
  • Computationally expensive (when compared to simple filters)

Input

  • A binary/grayscale image hilighting the line-pixels in the input image

Output

  • A list of the positions/orientations of the lines detected in the input image
