Annotation

The annotation file is a Python dictionary that has the following format: p2d is a numpy array of shape (num_keypoints, 2) that stores the image coordinates of the 2D key-points. Each row in the array stores (x, y) coordinate of the corresponding key-point. These key-points are re-annotated with a style similar to that of Human 3.6M, and can be accessed through key 'h36m'. lsp is a boolean flag that indicates whether the image is collected from Leeds Sport Pose dataset or not.

{
'image_name1':{'p2d':array1, 'lsp':True/False, 'h36m':array2},
'image_name2':{'p2d':array3, 'lsp':True/False, 'h36m':array4},
...
}
