Porting Segment Anything: SAM2 in ONNX/C++, SAM3 in thin scripts
Learn how to port Segment Anything models (SAM2/SAM3) to C++/ONNX and thin scripts for interactive segmentation demos on Windows CUDA or macOS Apple Silicon.
Overview
I built a portable interactive segmentation stack around Segment Anything: a C++/ONNX Runtime wrapper for SAM2 plus thin SAM3 image/video demo scripts that run on Windows CUDA or macOS Apple Silicon. In the demo I’ll show prompt-driven segmentation and video propagation, then pop the hood on how I split the model/runtime pieces so the same workflow runs outside research notebooks.
