Torchreid

A research toolkit for training AI that recognises the same person across different camera images.

Research-backedNew this week

What it does

Torchreid is a code library for person re-identification. This is the task of teaching a computer to tell whether people in photos or video clips taken by different cameras are the same person. It is written in PyTorch, a popular toolkit for building AI.

It helps researchers prepare common datasets, train models on one or more of them, and test how well the models work. It includes ready-made versions of several published models, including OSNet from the makers' own research, plus pretrained models you can download.

It also offers tools for viewing results and for exporting trained models to other formats such as ONNX, OpenVINO and TFLite, so they can run in other software.

Who it's for

Researchers and developers working on computer vision who want to train or compare person re-identification models.

Can I use it without coding?

Developers only. Using it means installing Python tools and writing or running Python code to train and test models. New to this? Start here.
