A good description is on this page.
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
