Abstract
In most literatures, contour of a region R is defined as the set of pixels in R that have at least a neighbor outside R . Applying this definition to images with multi-labels, for example, results of segmentation, one will end up with nonoverlapping boundaries between regions. This contradicts with the definition of contour in analog plane and makes shape analysis among regions difficult. This paper uses the concept of extended boundary [FP75][Pa77] and presents a new, efficient contour tracing algorithm that maintains common boundaries between regions. It is shown that, in additional to the common boundary representation, the new algorithm has many advantages over the old approaches.
