Hough Transform
Designed specifically to find lines
- Lines are defined as the collection of edge points
- Find all the lines on which edge points lie
The primary advantage of the Hough transform is that it reduces the search time for finding lines and the corresponding set of points.
Basic Idea
Hough Space
Quantization of parameter space
Large quantization block
-> reducing search time ->less line resolution
