Keypoint Detection

Keypoint detection is a crucial technique in computer vision for analyzing and interpreting images, aiming to simultaneously detect and locate points of interest within an image. These keypoints are spatial or spatiotemporal positions with distinctive features that are invariant to transformations such as rotation, scaling, translation, and distortion in the image. Keypoint detection has significant application value in areas like pose estimation, object detection and tracking, facial analysis, and augmented reality.
