# YOLO-Series ONNXRuntime Rust Demo for Core YOLO Tasks

This repository provides a Rust demo for key YOLO-Series tasks such as `Classification`, `Segmentation`, `Detection`, `Pose Detection`, and `OBB` using ONNXRuntime. It supports various YOLO models (v5 - 11) across multiple vision tasks.

## Introduction

- This example leverages the latest versions of both ONNXRuntime and YOLO models.
- We utilize the [usls](https://github.com/jamjamjon/usls/tree/main) crate to streamline YOLO model inference, providing efficient data loading, visualization, and optimized inference performance.

## Features

- **Extensive Model Compatibility**: Supports `YOLOv5`, `YOLOv6`, `YOLOv7`, `YOLOv8`, `YOLOv9`, `YOLOv10`, `YOLO11`, `YOLO-world`, `RTDETR`, and others, covering a wide range of YOLO versions.
- **Versatile Task Coverage**: Includes `Classification`, `Segmentation`, `Detection`, `Pose`, and `OBB`.
- **Precision Flexibility**: Works with `FP16` and `FP32` ONNX models.
- **Execution Providers**: Accelerated support for `CPU`, `CUDA`, `CoreML`, and `TensorRT`.
- **Dynamic Input Shapes**: Dynamically adjusts to variable `batch`, `width`, and `height` dimensions for flexible model input.
- **Flexible Data Loading**: The `DataLoader` handles images, folders, videos, and video streams.
- **Real-Time Display and Video Export**: `Viewer` provides real-time frame visualization and video export functions, similar to OpenCV’s `imshow()` and `imwrite()`.
- **Enhanced Annotation and Visualization**: The `Annotator` facilitates comprehensive result rendering, with support for bounding boxes (HBB), oriented bounding boxes (OBB), polygons, masks, keypoints, and text labels.

## Setup Instructions

### 1. ONNXRuntime Linking

<details>
<summary>You have two options to link the ONNXRuntime library:</summary>

- **Option 1: Manual Linking**

  - For detailed setup, consult the [ONNX Runtime linking documentation](https://ort.pyke.io/setup/linking).
  - **Linux or macOS**:
    1. Download the ONNX Runtime package from the [Releases page](https://github.com/microsoft/onnxruntime/releases).
    2. Set up the library path by exporting the `ORT_DYLIB_PATH` environment variable:
       ```shell
       export ORT_DYLIB_PATH=/path/to/onnxruntime/lib/libonnxruntime.so.1.19.0
       ```

- **Option 2: Automatic Download**
  - Use the `--features auto` flag to handle downloading automatically:
    ```shell
    cargo run -r --example yolo --features auto
    ```

</details>

### 2. \[Optional\] Install CUDA, CuDNN, and TensorRT

- The CUDA execution provider requires CUDA version `12.x`.
- The TensorRT execution provider requires both CUDA `12.x` and TensorRT `10.x`.

### 3. \[Optional\] Install ffmpeg

To view video frames and save video inferences, install `rust-ffmpeg`. For instructions, see:
