# OpenReshoot SHARP Core ML Package

This repository hosts the Core ML package used by OpenReshoot for on-device
single-image view synthesis experiments on iOS.

The model is a Core ML conversion of Apple's SHARP research checkpoint. SHARP
predicts a 3D Gaussian representation from one input image, enabling nearby
view rendering from a single photograph.

## Files

```text
SHARP.mlpackage/
  Manifest.json
  Data/com.apple.CoreML/model.mlmodel
  Data/com.apple.CoreML/weights/weight.bin
```

OpenReshoot downloads these files and reconstructs the `SHARP.mlpackage`
directory locally.

## Intended Use

- Research and experimentation with monocular view synthesis.
- OpenReshoot iOS builds that download the model instead of bundling it inside
  the app.
- Local Core ML testing of the converted SHARP model.

## Not Intended For

- Commercial products or services.
- General-purpose photo editing, identity editing, surveillance, or biometric
  use.
- Text-to-image generation or image restoration. This package is for SHARP's
  single-image 3D representation prediction path.

## Source And Conversion

Upstream project:

- Apple ML SHARP: https://github.com/apple/ml-sharp
- Project page: https://apple.github.io/ml-sharp/
- Paper: https://arxiv.org/abs/2512.10685

The upstream checkpoint is converted to Core ML for OpenReshoot using the
conversion tooling in the OpenReshoot repository.
