The conventional approach to Image Segmentation in early visual processing is Edge Detection followed by boundary detection. Edge detection produces primitive edge elements, possibly with properties of magnitude and/or direction, at places in the image where the edge detection operator has `fired'. The task of the boundary detection process is to produce a set of boundaries by appropriately connecting up primitive edge elements. There are two main methods:
- boundary tracking, and
- the generalised Hough Transform.
