Implementation of Concave Point Detection Using Harry's Algorithm

In this document, we introduce how to implement concave point detection using Harry's algorithm on the MATLAB platform. First, we provide a detailed explanation of Harry's algorithm and its underlying principles for concave point detection, including the mathematical foundation and key computational steps involved. Then, we explore the MATLAB implementation of this algorithm, presenting detailed implementation steps and code examples that demonstrate critical functions such as point cloud processing, curvature calculation, and concave feature identification. Additionally, we discuss how to enhance detection accuracy by adjusting algorithm parameters, covering parameter optimization techniques and practical implementation tips. The implementation includes MATLAB code for handling different input formats, configuring detection thresholds, and visualizing results. Finally, we summarize the main content of this document and provide reference materials to help readers gain deeper understanding of the topic, including suggested MATLAB toolboxes and alternative implementation approaches.
