Contour Tracing Algorithms. The following algorithms will ignore any "holes" present in the pattern. For example, if we're given a pattern like that of Figure 1 below, the contour traced by the algorithms will be similar to the one shown in Figure 2 (the blue pixels represent the contour). This could be acceptable in some applications but in other applications, like character …

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 ...

Short explanation of how the algorithm works. Pad the image with a white 1 pixel wide border. Start scanning from the top-left position and scan each pixel from left to right downwards. When a black pixel is found, trace around the contour in a clockwise direction. Tracing the contour is done by checking the 8 neighbors and see if they are black.

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 …
