OpenPose Library - Release Notes

OpenPose 1.0.0rc1

  1. Initial version, main functionality:
    1. Body keypoint detection and rendering on Ubuntu 14 and 16.
    2. It can read an image directory, video or webcam.
    3. It can display the results or storing them on disk.

OpenPose 1.0.0rc2

  1. Main improvements:
    1. Rendering max resolution from 720p to >32k images.
    2. Highly improved documentation.
  2. Functions or parameters renamed:
    1. Demo renamed from rtpose to openpose.
  3. Main bugs fixed:
    1. Demo uses exec instead of start, so it works with more OpenCV custom compiled versions.

OpenPose 1.0.0rc3

  1. Main improvements:
    1. Added face keypoint detection.
    2. Added Windows 10 compatibility.
    3. Auto-detection of the number of GPUs.
    4. MPI visualization more similar to COCO one.
    5. Rendering max resolution from 720p to >32k images.
    6. GUI info adder working when the worker TDatum has more than 1 Datum.
    7. It prints out the error description before throwing the exception (so that it is written on the Windows cmd).
    8. Highly improved documentation.
  2. Functions or parameters renamed:
    1. Flag write_pose renamed as write_keypoint and it also applies to face and/or hands.
    2. Flag write_pose_json renamed as write_keypoint_json and it also applies to face and/or hands.
    3. Flag write_pose_format renamed as write_keypoint_format and it also applies to face and/or hands.
    4. PoseSaver and its JSON variant renamed as KeypointSaver.
    5. PoseJsonCocoSaver renamed as CocoJsonSaver.
  3. Main bugs fixed:
    1. All visualization functions moved to same thread, so it works with most OpenCV custom compiled versions.
    2. Fixed error on debug mode: Too many resources requested for launch.

Current version (future OpenPose 1.0.0rc4)

  1. Main improvements:
    1. Increased accuracy on multi-scale (added Datum::scaleRatios to save the relative scale ratio when multi-scale).
    2. Increased speed ~3-5% by adding CPU rendering and setting it as default rendering.
    3. Check() functions give more feedback.
    4. WCocoJsonSaver finished and removed its 3599-image limit.
    5. Added camera_fps so generated video will use that frame rate.
    6. Improved documentation.
  2. Functions or parameters renamed:
    1. Render flags renamed in the demo in order to incorporate the CPU/GPU rendering.
  3. Main bugs fixed:
    1. Fixed bug in Array::getConstCvMat() if mVolume=0, now returning empty cv::Mat.
    2. Fixed bug: --process_real_time threw error with webcam.
    3. Fixed bug: Face not working when input and output resolutions are different.
    4. Fixed some bugs that prevented debug version to run.
