# Note: We highly recommend to reduce `--output_resolution`. E.g. for 3 cameras recording at 1920x1080, the resulting image is (3x1920)x1080, so we recommend e.g. 1920x360 (x3 reduction).
15. Camera parameters (flir camera) are read from disk at runtime rather than being compiled.
16. 3-D reconstruction module can be implemented with different camera brands or custom image sources.
17. Flag `--write_json` includes 3-D keypoints.
18.Flag `--image_dir_stereo` added to allow `--image_dir` to load stereo images.
18.3-D reconstruction module can be used with images and videos. Flag `--3d_views` added to allow `--image_dir` and `--video` allow loading stereo images.
19. Flag `--camera_resolution` applicable to `--flir_camera`.
20. Throw error message if requested GPU IDs does not exist (e.g. asking for 2 GPUs starting in ID 1 if there is only 2 GPUs in total).
21. VideoSaver (`--write_video`) compatible with multi-camera setting. It will save all the different views concatenated.
2. Functions or parameters renamed:
1. Flag `no_display` renamed as `display`, able to select between `NoDisplay`, `Display2D`, `Display3D`, and `DisplayAll`.
2. 3-D reconstruction demo is now inside the OpenPose demo binary.
