YoloSharp 6.0.0

YoloSharp

Use YOLO11 in real-time for object detection tasks 🚀 with edge performance ⚡️ powered by ONNX-Runtime.

Features

• YOLO Tasks 🌟 Support for all YOLO vision tasks (Detect | OBB | Pose | Segment | Classify)
• High Performance 🚀 Various techniques and use of .NET features to maximize performance
• Reduced Memory Usage 🧠 By reusing memory blocks and reducing the pressure on the GC
• Plotting Options ✏️ Draw the predictions on the target image to preview the model results
• YOLO Versions 🔧 Includes support for: YOLOv8 YOLOv10 YOLO11

Installation

This project provides two NuGet packages:

• For CPU inference, use the package: YoloSharp (includes the Microsoft.ML.OnnxRuntime package)
• For GPU inference, use the package: YoloSharp.Gpu (includes the Microsoft.ML.OnnxRuntime.Gpu package)

Usage

1. Export model to ONNX format:

For convert the pre-trained PyTorch model to ONNX format, run the following Python code:

from ultralytics import YOLO

# Load a model
model = YOLO('path/to/best.pt')

# Export the model to ONNX format
model.export(format='onnx')

2. Load the ONNX model with C#:

Add the YoloSharp (or YoloSharp.Gpu) package to your project:

dotnet add package YoloSharp

Use the following C# code to load the model and run basic prediction:

using Compunet.YoloSharp;

// Load the YOLO predictor
using var predictor = new YoloPredictor("path/to/model.onnx");

// Run model
var result = predictor.Detect("path/to/image.jpg");
// or
var result = await predictor.DetectAsync("path/to/image.jpg");

// Write result summary to terminal
Console.WriteLine(result);

Plotting

You can to plot the target image for preview the model results, this code demonstrates how to run a inference, plot the results on image and save to file:

using Compunet.YoloSharp;
using Compunet.YoloSharp.Plotting;
using SixLabors.ImageSharp;

// Load the YOLO predictor
using var predictor = new YoloPredictor("path/to/model.onnx");

// Load the target image
using var image = Image.Load("path/to/image");

// Run model
var result = await predictor.PoseAsync(image);

// Create plotted image from model results
using var plotted = await result.PlotImageAsync(image);

// Write the plotted image to file
plotted.Save("./pose_demo.jpg");

You can also predict and save to file in one operation:

using Compunet.YoloSharp;
using Compunet.YoloSharp.Plotting;
using SixLabors.ImageSharp;

// Load the YOLO predictor
using var predictor = new YoloPredictor("path/to/model.onnx");

// Run model, plot predictions and write to file
predictor.PredictAndSaveAsync("path/to/image");
