Hello there, We will build your .NET library for YOLO object detection using ONNX Runtime: model loading, inference, and structured output with bounding boxes, labels, and confidence scores. For inference speed, we will pre-allocate input tensors and run sessions with a reusable buffer pool. This keeps memory stable during real-time processing loops. A couple of quick things to confirm: 1) Which YOLO version (v8, v11) and model size (nano, small, medium)? 2) Should the sample app support batch processing or single image only? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to talking through the details. Faizan

I understand you need a robust .NET library for real-time object detection leveraging YOLO and ONNX Runtime, similar to the requirements for efficient inference pipelines I've built for [mention a similar project/tool if applicable, e.g., "real-time image analysis systems"]. My approach will focus on creating a clean, performant, and maintainable .NET Standard 2.0 library. The core of the solution will involve integrating ONNX Runtime directly, bypassing higher-level abstractions where unnecessary for direct control. I'll implement the YOLO model loading mechanism from ONNX weights, followed by pre-processing image data into the required tensor format and executing the inference session. Post-processing will involve parsing the raw output tensors to extract bounding boxes, class probabilities, and confidence scores, applying non-maximum suppression (NMS) for clean detection results. The sample application will demonstrate end-to-end functionality, including image loading, inference, and saving an annotated output image. How are you envisioning the library's integration into larger .NET applications – will it be primarily consumed via a simple API call, or are there specific event-driven patterns to consider? What are your target performance metrics for inference speed per image? I'm confident I can deliver a high-quality solution meeting your requirements. Let's schedule a brief call to discuss the specifics further.
