Samples of annotations of the 3rd metacarpal and 5th metacarpal (red), 3rd proximal phalanx, 5th proximal phalanx (green), 3rd distal phalanx and 5th distal phalanx (blue), and the 1st proximal phalanx (purple). There is an overlap of the red and green boxes, which indicates that the prediction of the 3rd and 5th metacarpal and the 3rd and 5th proximal phalanx will be more difficult than the prediction of the 1st proximal phalanx
