This project is a tool for annotating 2D poses in fingerprint images. It provides two modes for users:

• Direct Annotation: Users can directly mark the center and direction of fingerprints.

• Annotation by Manual Alignment: Users can obtain the pose by manually aligning two fingerprints, where the pose of one of them is known.

The format of pose2d file is as follows: center_x, center_y, direction_in_degree.
