Demo of HMR.
Note that HMR requires the bounding box of the person in the image. The best performance is obtained
when max length of the person in the image is roughly 150px.
When only the image path is supplied, it assumes that the image is centered on a person whose length
is roughly 150px.
Alternatively, you can supply output of the openpose to figure out the bbox and the right scale fact
or.
Sample usage:
# On images on a tightly cropped image around the person
python -m demo --img_path data/im1963.jpg
python -m demo --img_path data/coco1.png
# On images, with openpose output
python -m demo --img_path data/random.jpg --json_path data/random_keypoints.json
