Change Log

Major updates and new features to this project will be listed in this document.

August 3, 2021

• Added Pose Estimation with PoseNet with pre-trained models
• Added Mononocular Depth with DepthNet with pre-trained models
• Added support for cudaMemcpy() from Python
• Added support for drawing 2D shapes with CUDA

August 31, 2020

• Added initial support for Running in Docker Containers
• Changed OpenGL behavior to show window on first frame
• Minor bug fixes and improvements

July 15, 2020

note: API changes from this update are intended to be backwards-compatible, so previous code should still run.

• Re-training SSD-Mobilenet Object Detection tutorial with PyTorch
• Support for collection of object detection datasets and bounding-box labeling in camera-capture tool
• videoSource and videoOutput APIs for C++/Python that supports multiple types of video streams:
  • MIPI CSI cameras
  • V4L2 cameras
  • RTP / RTSP
  • Videos & Images
  • Image sequences
  • OpenGL windows
• Unified the -console and -camera samples to process both images and video streams
  • imagenet.cpp / imagenet.py
  • detectnet.cpp / detectnet.py
  • segnet.cpp / segnet.py
• Support for uchar3/uchar4/float3/float4 images (default is now uchar3 as opposed to float4)
• Replaced opaque Python memory capsule with jetson.utils.cudaImage object
  • See Image Capsules in Python for more info
  • Images are now subscriptable/indexable from Python to directly access the pixel dataset
  • Numpy ndarray conversion now supports uchar3/uchar4/float3/float4 formats
• cudaConvertColor() automated colorspace conversion function (RGB, BGR, YUV, Bayer, grayscale, ect)
• Python CUDA bindings for cudaResize(), cudaCrop(), cudaNormalize(), cudaOverlay()
  • See Image Manipulation with CUDA and cuda-examples.py for examples of using these
• Transitioned to using Python3 by default since Python 2.7 is now past EOL
• DIGITS tutorial is now marked as deprecated (replaced by PyTorch transfer learning tutorial)
• Logging can now be controlled/disabled from the command line (e.g. --log-level=verbose)

Thanks to everyone from the forums and GitHub who helped to test these updates in advance!

October 3, 2019
