Within the MATLAB environment, contour tracing algorithms can be employed to extract numerical arrays representing image boundaries, along with relevant measurement positions and contour properties. These algorithms facilitate deeper understanding of image structures and features, enabling subsequent analysis and processing. Through contour tracing implementation (typically using functions like bwboundaries or custom edge-following logic), pixel coordinates along boundaries can be obtained, allowing calculation of geometric measurements including contour length, enclosed area, and shape descriptors. Such measurements hold significant value in domains like image processing, pattern recognition, and computer vision applications. The algorithm workflow generally involves binary image preprocessing, seed point detection, and directional tracing using connectivity rules (4-connected or 8-connected neighborhoods) to form closed contours.
