# OpenCV Zoo

A zoo for models tuned for OpenCV DNN with benchmarks on different platforms.

Guidelines:
- To clone this repo, please install [git-lfs](https://git-lfs.github.com/), run `git lfs install` and use `git lfs clone https://github.com/opencv/opencv_zoo`.
- To run benchmark on your hardware settings, please refer to [benchmark/README](./benchmark/README.md).

## Models & Benchmarks

Hardware Setup:
- `CPU x86_64`: INTEL CPU i7-5930K @ 3.50GHz, 6 cores, 12 threads.
- `CPU ARM`: Raspberry 4B, BCM2711B0 @ 1.5GHz (Cortex A-72), 4 cores, 4 threads.
<!--
- `GPU CUDA`: NVIDIA Jetson Nano B01, 128-core Maxwell, Quad-core ARM A57 @ 1.43 GHz.
-->

***Important Notes***:
- The time data that shown on the following tables presents the time elapsed from preprocess (resize is excluded), to a forward pass of a network, and postprocess to get final results.
- The time data that shown on the following tables is averaged from a 100-time run.
- View [benchmark/config](./benchmark/config) for more details on benchmarking different models.
