The following command will save all the body part heat maps, background heat map and Part Affinity Fields (PAFs) in the folder `output_heatmaps_folder`. It will save them on PNG format. Instead of individually saving each of the 67 heatmaps (18 body parts + background + 2 x 19 PAFs) individually, the library concatenate them vertically into a huge (width x #heatmaps) x (height) matrix. The PAFs channels are multiplied by 2 because there is one heatmpa for the x-coordinates and one for the y-coordinates. The order is body parts + bkg + PAFs. It will follow the sequence on POSE_BODY_PART_MAPPING in [include/openpose/pose/poseParameters.hpp](../include/openpose/pose/poseParameters.hpp).

## Heat Maps Storing
The following command will save all the body part heat maps, background heat map and Part Affinity Fields (PAFs) in the folder `output_heatmaps_folder`. It will save them on PNG format. Instead of individually saving each of the 67 heatmaps (18 body parts + background + 2 x 19 PAFs) individually, the library concatenate them vertically into a huge (width x #heatmaps) x (height) matrix.

## Basic Output Saving
The following example runs the demo video `video.avi`, renders image frames on `output/result.avi`, and outputs JSON files in `output/`. It parallelizes over 2 GPUs, GPUs 1 and 2 (note that it will skip GPU 0):
