# Jacinto-AI-Detection

This repository is an extension of the popular [mmdetection](https://github.com/open-mmlab/mmdetection) open source repository for object detection training. While mmdetection focuses on a wide variety of models, typically at high complexity, we focus on models that are optimized for speed and accuracy so that they run efficiently on embedded devices. 

Kindly take time to read through the documentation of the original [mmdetection](https://github.com/open-mmlab/mmdetection) before attempting to use this repository.

Also, please read the documentation at our landing page [jacinto-ai-devkit](https://github.com/TexasInstruments/jacinto-ai-devkit) before using this repository.


## Installation

This repository requires [**mmdetection**](https://github.com/open-mmlab/mmdetection) and [**mmcv**](https://github.com/open-mmlab/mmcv) to be installed. 

Please refer to [installation instructions for mmdetection](https://github.com/open-mmlab/mmdetection/blob/master/docs/install.md) for installation instructions. If you get any issues with the master branch of mmdetection, please try after checking out the latest release tag. After installation, a python package called "mmdet" will be listed if you do *pip list*

To install mmcv, browse to the github page of [mmcv](https://github.com/open-mmlab/mmcv), and see the section that says "**Install with pip**". Install the full version of mmcv using the instruction given there. Please check your CUDA version and PyTorch version and select the appropriate installation instructions.

After installing **mmdetection** and **mmcv**, please clone and install [**PyTorch-Jacinto-AI-DevKit**](https://git.ti.com/cgit/jacinto-ai/pytorch-jacinto-ai-devkit/about/) using the link given in [jacinto-ai-devkit](https://github.com/TexasInstruments/jacinto-ai-devkit) as this repository uses several components from there - especially to define low complexity models and to do Quantization Aware Training (QAT) or Calibration.

Please see our minimal installation script [setup.sh](./setup.sh) and modify for your system.

## Get Started

Please see [Getting Started with MMDetection](https://github.com/open-mmlab/mmdetection/blob/master/docs/getting_started.md) for the basic usage of mmdetection. Note: Some of these may not apply to this repository.

Please see [Usage](./docs/det_usage.md) for training and testing with this repository.


## Benchmark and Model Zoo

Accuracy report of several trained models is available at the [Detection Model Zoo](./docs/det_modelzoo.md) 


## Quantization

This tutorial explains how to do [Quantization Aware Training (QAT)](./docs/det_quantization.md) of detection models.


## ONNX & Prototxt Export
**Export of ONNX model (.onnx) and additional meta information (.prototxt)** is supported. The .prototxt contains meta information specified in **[TIDL](https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos_auto/docs/user_guide/sdk_components.html#ti-deep-learning-library-tidl)** for object detectors. 

The export of meta information is now supported for **SSD** and **RetinaNet** detectors.

For more information please see [Usage](./docs/det_usage.md)


## Acknowledgement

This is an open source project that is contributed by researchers and engineers from various colleges and companies. We appreciate all the contributors who implement their methods or add new features, as well as users who give valuable feedbacks.

We wish that the toolbox and benchmark could serve the growing research community by providing a flexible toolkit to train existing detectors and also to develop their own new detectors.
