Keypoint Preserving Coordinate Transformation

via “keypoint-preserving coordinate transformation”

Fast image augmentation library with 70+ transforms.

Unique: Applies geometric transformations to keypoint coordinates using the same transformation matrix as the image, preserving spatial relationships and supporting multi-keypoint objects with visibility flags — unlike manual coordinate transformation or frameworks that treat keypoints as independent data

vs others: Automatically synchronizes keypoint coordinates with image transforms without separate transformation code, reducing annotation errors and enabling augmentation of pose estimation datasets that require pixel-perfect coordinate alignment
