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.

OpenPose 1.0.0

  1. Main improvements:
    1. Added hand keypoint detection.
    2. Windows branch merged to master branch.
    3. Face and hands use Maximum instead of Nms, since there is only 1 person / detection.
    4. Increased accuracy on multi-scale (added Datum::scaleRatios to save the relative scale ratio when multi-scale).
    5. Increased speed ~5% by adding CPU rendering (but GPU is the default rendering).
    6. Rendering colors modified, visually better results.
    7. Rendering threshold for pose, face and hands becomes user-configurable.
    8. Check() functions give more feedback.
    9. WCocoJsonSaver finished and removed its 3599-image limit.
    10. Added camera_fps so generated video will use that frame rate.
    11. Reduced the number of printed information messages. Default logging priority threshold increased to Priority::Max.
    12. Google flags to OpenPose configuration parameters reader moved from each demo to utilities/flagsToOpenPose.
    13. Nms classes do not use numberParts for Reshape, they deduce the value.
    14. Improved documentation.
  2. Functions or parameters renamed:
    1. Render flags renamed in the demo in order to incorporate the CPU/GPU rendering.
    2. Keypoints saved in JSON files (write_keypoint_json) are now saved as pose_keypoints, face_keypoints, hand_left_keypoints, and hand_right_keypoints. They all were previously saved as body_parts.
    3. Flag num_scales renamed as scale_number.
    4. All hand and pose flags renamed such as they start by hand_ and face_ respectively.
  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.
    5. Face saved in JSON files were called body_parts. Now they are called face_keypoints.

OpenPose 1.0.1

  1. Main improvements:
    1. Windows library turned into DLL dynamic library (i.e. portable).
    2. Improved documentation.
  2. Functions or parameters renamed:
    1. openpose/utilities/macros.hpp moved to openpose/utilities/macros.hpp.

Current version (future OpenPose 1.0.2)

  1. Main improvements:
    1. Caffe turned into DLL library.
    2. Added OpenPose 1.0.1 portable demo.
  2. Main bugs fixed:
    1. Pycaffe can now be imported from Python.
