https://www.codeproject.com/articles/196168/contour-analysis-for-image-recognition-in-c
In the core, it concerns some aspects of the theory, and also problems of optimization of algorithms of the contour analysis. The second part of the article is devoted to it. In the same place results of work of algorithms are brought, problems and deficiencies of the given method are described. The third part describes C# library ContourAnalysis.
Fast Contour-Tracing Algorithm Based on a Pixel …
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4813928/
In this paper, we propose a novel contour-tracing algorithm based on pixel following that overcomes the above-mentioned problems, i.e.,: (1) it provides fast and accurate results for contour-pixel tracing; (2) contour information can be compressed to reduce the memory size; and (3) it accurately restores the compressed data to the original contour image. …

Fast contour tracing algorithm Square Tracing algorithm This was one of the first approaches to extract contours and is quite simple. Suppose background is black (0’s) and object is white (1’s). Start iterating over the binary or segmented image row by row starting from left to right. If you detect white pixel (i.e. 1) go left otherwise go right.
