Could you build this?
Partial While existing Segment Anything (SAM) models can be downloaded, optimizing inference to run smoothly on CPU via memory-aware video chunking requires specialized knowledge of ONNX/ggml quantizations and tensor memory layouts.
What it would actually take: The system requires wrapping Meta's SAM architecture into an ONNX Runtime or C++ (ggml/llama.cpp-style) inference pipeline optimized for AVX-512/NEON instructions. The tricky part is designing the temporal memory management and sliding-window chunking algorithms so multi-minute video frames do not exhaust system RAM during cross-frame feature mask propagation. Expertise in machine learning model optimization, quantization, and tensor memory management is required.
