Change log

v0.9.0

  • [Breaking Change] Downgraded the SDK dependency to CUDA 10.0 (from CUDA 10.1). ONNX runtime officially only supports up to CUDA 10.0.
  • [Breaking Change] Switched to ONNX runtime instead of Tensorflow runtime. Reduces the first frame launching time and memory usage. It also reduces the SDK binary size.
  • [API Change] Renamed k4abt_tracker_queue_capture() to k4abt_tracker_enqueue_capture()
  • [API Change] Broke k4abt_frame_get_body() into two separate functions: k4abt_frame_get_body_skeleton() and k4abt_frame_get_body_id(). Now you can query the body ID without always copying the whole skeleton structure.
  • [API Change] Added k4abt_frame_get_timestamp_usec() function to simplify the steps for the users to query body frame timestamp.
  • Further improved the body tracking algorithm accuracy and tracking reliability

v0.3.0

  • [Breaking Change] Added support for NVIDIA RTX GPUs by moving to CUDA 10.1 dependency
  • [API Change] Provide the joint output in millimeters to be consistent with the Kinect for Windows v2 SDK
  • Further improved the body tracking algorithm accuracy and reliability.
