Keypoints Computer Vision
noun
Definition: Specific, repeatable coordinates or points of interest in an image that mark salient local features and help a vision system represent shape, structure, pose, or correspondence across images. In many application areas, especially pose estimation and face analysis, these points function as landmarks [Budzan et al. 2025].
Example in context: “Accurate detection of keypoints enables detailed motion analysis, which is essential for tasks such as video surveillance and sports analytics.” [Huang et al. 2025]
Synonyms: landmarks (context-dependent; especially in facial, anatomical, or pose-estimation tasks); feature points
