Contour Tracing Algorithms. What follows are four of the most common contour tracing algorithms. The first two, namely: the Square Tracing algorithm and Moore-Neighbor Tracing are easy to implement and are therefore used frequently to trace the contour of a given pattern. Unfortunately, both of these algorithms have a number of weaknesses which ...

Output: A sequence B (b1, b2 ,..., bk) of boundary pixels i.e. the contour. Begin. Set B to be empty. From bottom to top and left to right scan the cells of T until a black pixel, s, of P is found. Insert s in B. Set the current pixel, p, to be the starting pixel, s. Turn left i.e. visit the left adjacent pixel of p.

Boundary tracing - Wikipedia
https://en.wikipedia.org/wiki/Boundary_Tracing
Boundary tracing, also known as contour tracing, of a binary digital region can be thought of as a segmentation technique that identifies the boundary pixels of the digital region. Boundary tracing is an important first step in the analysis of that region. Boundary is a topological notion. However, a digital image is no topological space. Therefore, it is impossible to define the notion of a …

Fig. 5 shows an example of how the square tracing algorithm starting at the pixel marked S produces a sequence of boundary pixels in the case P is 8-connected. It would be nice to be able to prove that Algorithm Square-Tracing always works correctly, i.e., that for all connected patterns it extracts the entire set of boundary pixels as defined ...
