• "a str of ten-digit integer" is a string of code which represends a specific image folder. It is corresponding to one activity.
• "person_ID" is an integer between 1,2,3,4 due to the data were collected from four person.
• "folder_path" is the location of image folder. In CAD-60 dataset, RGB and depth images are sotred in one folder. The folder code is linked to a str of ten0digit interger.
• "action_label" refers to the action that it belongs to.
• "frames" stores all data in "folder_path", you can search by image ID.
• "ID" is the interger begins from 1. It is refers to the image ID.
• "ROI" is orientation of the joints.
• "Joint ID" is an interger begins from 0, end in 10. In CAD dataset, there are only 11 joints include the orientation.
• "orin" is a list with 9 elements.
• "CONF" is the boolean confidence value (0 or 1).
• "P" refers to joint points.
• "coor" is a list with 3 elements, which are x,y,z. The origin of the corridinate system is at the sensor.
