OmniTrax Version 0.2.2

The latest version of OmniTrax now adds support for footage masking and advanced sample export (see tutorial-tracking for details). Users can now specify in which regions they want to run inference, to, e.g. exclude reflections or animals outside the region of interest. Advanced sample export can be used to extract cropped image patches of individual animals for further analysis or to inform the training of other specialised networks.

GPU inference compatibility with the latest release of Blender LTS 3.3!

OmniTrax is built for Windows 10 / 11.

Simply install the omni_trax.zip file from within Blender in the Addon tab, as described in the README. No need to unpack the file, but make sure to run Blender in Administrator mode for the installation of this addon as additional python packages will be installed automatically.

Notes on GPU version [recommended]

Install the correct CUDA & cudNN versions (11.2 and 8.1 respectively) mentioned in the readme for GPU support. The DLLs have been built specifically to run on machines with dedicated NVIDIA GPUs with compute capability of 6.1 or higher.

Notes on CPU-only version

If you wish to run inference on CPU-only systems, you must use Blender version 2.9.2 instead to match dependencies!
