When running video analysis with cropping, the predicted poses are stored in the cropped image space. To get the coordinates of the pose in the space of the full video, the data stored in the
_metadata.picklecan be used.The
extract_outlier_framesandcreate_video_with_all_detectionsdid not take these offsets into account, meaning the video with all detections had its keypoints shifted, as did the machine labels.This PR fixes both of these issues.
As
create_video_with_all_detectionshas acroppingargument, the behavior is set such that:croppingis given as an argument, that value is used (overriding the value stored in the metadata)croppingis not given then metadata["data"]["cropping"] and metadata["data"]["cropping_parameters"] are used
