Strand Camera - low-latency single camera acquisition and tracking software

Strand Camera logo

Strand Camera is low-latency camera acquisition and tracking software. It is useful for 2D tracking of animals, robots, or other moving objects. It also serves as the basis for 3D tracking using Braid.

Strand Camera is the successor of fview, and is the result of a rewrite focused on performance, ease of use, and flexibility.

Features

  • Low-latency, marker-free 2D tracking of multiple animals based on high-performance background subtraction.
  • Tracking latency is dominated by image acquisition time, with all aspects of the program written to prioritize low latency image acquisition and processing.
  • Basler USB3 and GigE area cameras are supported
  • Recording of compressed video into MKV files with precise timestamps
    • VP8 and VP9 codecs use CPU compression and are available on all supported platforms
    • On supported Linux systems with appropriate NVIDIA hardware, H264 compression is performed
  • Web based user interface allowing easy remote control
  • Integrated Python scripting
    • Python-based image processing (e.g. with DeepLabCut)
    • Python-based control of all user interface elements in the web-based interface.

Supported operating system

Ubuntu Linux (64 bit Intel/AMD) is supported. We test internally on macOS and Windows.

Cost and licensing

Strand Camera is free software in alpha testing. Releases are provided via a private repository on GitHub. Please email Andrew Straw with your GitHub account name for access.

Access to the source code is possible upon agreement with Andrew Straw. We have the goal of open sourcing the software.

Support

Support is offered on a best effort basis via the github repository or the online forum. Contact Andrew Straw regarding for potential availability for collaboration, paid support, or custom development.
