| # Project Halide
|
|
|
| Project Halide is an edge-native diagnostic workbench for analog film scans by
|
| [Lonelyguyse1](https://huggingface.co/Lonelyguyse1).
|
|
|
| The runtime uses MiniCPM-V 4.6 for defect extraction and
|
| Nemotron-Mini-4B-Instruct for diagnostic reasoning. The vision pass combines
|
| full-frame inspection, tiled fallback for large scans, a conservative
|
| image-analysis validator for obvious scratches, and geometric filtering for
|
| sprocket or frame-edge artifacts. Model inference runs on the Space GPU runtime
|
| without cloud inference APIs.
|
|
|
| Fine-tuned vision model:

|
|
| Modal was used for offline training, held-out GPU evaluation, checkpoint upload,
|
| GGUF conversion, and Space deployment. The runtime app itself does not call
|
| Modal or any hosted inference API.
|
|
|
| ## How It Works
|
|
|
| 1. Upload a film scan, negative photo, or contact-sheet crop.
|
| 2. MiniCPM-V 4.6 extracts candidate defects as structured JSON.
|
| 3. The validator normalizes boxes, filters bad geometry, removes duplicate or
|
| sprocket-like edge artifacts, and adds high-precision scratch candidates
|
| when clear linear evidence is visible.
|
| 4. Nemotron-Mini-4B-Instruct reads the validated evidence plus user metadata and
|
| writes a lab-style diagnosis with physical fixes.
|
| 5. SQLite stores local diagnostic history so earlier runs can be reopened.
|
|
|
| ## Sponsor Usage
|
|
|
| - OpenBMB: MiniCPM-V 4.6 is the primary vision model, fine-tuned for film defect
|
| extraction and published at `Lonelyguyse1/halide-vision`.
|
| - NVIDIA: Nemotron-Mini-4B-Instruct produces the diagnostic report and keeps
|
| uncertain film metadata lower priority than visible evidence.
|
| - Modal: used offline for training, evaluation, checkpoint export, GGUF
|
| conversion, model upload, and Space deployment support.
|
| - OpenAI: source-control history includes the required attributed development
|
| work in the linked GitHub repository.
|
|
|
| ## Field Guide Alignment
|
|
|
| - Gradio Space under the official `build-small-hackathon` organization.
|
| - All runtime inference uses open weights on the Space GPU, with no hosted model
|
| API calls.
|
| - Model sizes stay under the 32B limit, with MiniCPM-V 4.6 at 1.3B parameters
|
| and Nemotron-Mini-4B-Instruct at 4B parameters.
|
| - Custom autumn-themed UI with a purpose-built compare viewer and diagnostic
|
| history.
|
| - Fine-tuned vision model and GGUF artifact are published on the author's
|
| Hugging Face profile.
|
| - Demo video, technical blog, public launch post, and field notes are linked
|
| from this Space.
|
|
|
| Held-out validation summary:
|
|
|
| - Four visibly damaged private negatives were detected with scratch and
|
| emulsion-damage evidence.
|
| - One near-clean private negative returned zero defects.
|
| - A broad lifted crack network that failed full-frame inference was recovered by
|
| the tiled fallback.
