(Here)[[https://github.com/VectorElectron/yolov11\](https://github.com/VectorElectron/yolov11%5C)] is a sleek, professional, and exciting draft for your post, tailored for platforms like GitHub, LinkedIn, or developer forums (like WeChat Moments or Twitter/X). ## 🚀 Fully End-to-End YOLO: Merging Resize, Core Model, and NMS into a Single ONNX File! Tired of dealing with messy preprocessing (resize/normalization) and heavy Python/C++ post-processing (NMS) outside of your model? I’ve wrapped the **entire pipeline** —from raw uint8 images to final bounding boxes—into **one single ONNX file**. This approach delivers true **plug-and-play, end-to-end deployment** for web frontends, edge devices, or localized runtimes. ### 🌟 Key Features - **Zero-Dependency Pipeline** : No more manual bounding box parsing or custom NMS C++ modules. The model accepts a raw `[H, W, 3]` uint8 image and outputs final, scaled coordinates directly. - **Mathematical NMS** : Uses a batch-and-class isolated IoU graph lookup table (LUT) implemented directly in PyTorch operators—fully compatible with ONNX export. - **Fully Dynamic Input** : Supports dynamic image resolutions, automatically scaling coordinates back to the original input size. - **Seamless Merging** : Combines three independent stages (Preprocess, Core YOLO, and Post-NMS) into a unified computational graph using `onnx.compose`. ---
