| # Image Studio browser model resources |
|
|
| Browser-oriented model/runtime resources for Image Studio app 1.1.2. Photos are |
| processed locally in the user's browser; this repository does not receive photos |
| or provide inference. These are application-specific packs, not a generic |
| Transformers model loading layout. |
|
|
| ## Four explicit choices |
|
|
| - MODNet CPU and GPU share the same unchanged FP32 model. |
| - HR + ViTMatte GPU uses the fixed HR graph stages and three-phase full-key row8 |
| Loop MultiHeadAttention ViTMatte refinement, with CPU-owned phase seams. |
| - HR + ViTMatte CPU uses the recorded HR stages and separate three-phase |
| query-chunked ViTMatte derivative. CPU/GPU stage catalogs are not interchangeable. |
|
|
| The five ZIP_STORED packs preserve exact bytes, stream through the existing |
| verified cache importer and avoid whole-archive RAM expansion. Every declared |
| entry and transport has a byte count and SHA-256. MODNet transport is shared. |
| The CPU high-quality route is slow and memory intensive. No silent quality/model |
| fallback is provided. Interrupted downloads may require downloading a full pack |
| again; Hub service/rate limits and cache eviction can affect availability. |
| |
| ## Licenses and source |
| |
| Model weights, model code, ONNX Runtime and its third-party components retain |
| their own licenses. The app's MIT does not relicense them. LICENSES.md and all |
| original license/notice texts remain included. Source06 model-transform sources |
| retain the Swin MIT supplement and exclude the unused deployment adapter. |
| SOURCE_AVAILABILITY.md provides the fixed Eigen source/patches and source offer. |
| Historical review JSON records upstream export evidence, not current release |
| bindings or a claim of independent native/compiler rebuild. |
|
|
| ## Immutable release identity |
|
|
| APP_RELEASE_PAIRING.json is the release index. REPLAY.md gives the canonical |
| web/background-release placement. MODEL_FILES.json identifies the selected five |
| packs and all entries. App version and model graph identity are separate. The |
| index's review sourceId identifies its input review; later app-only updates bind |
| their own Git commit/build-info/inventory while retaining this immutable input. |
| Never put credentials in browser code or replace fixed resource URLs with main. |

| |
| ## Validation scope |
| |
| Local strict build and distribution inventory identify this artifact. Existing synthetic-portrait/cancellation/cache evidence is bounded, not general quality, mobile-device or physical-print certification. Saved outputs should be inspected. Anonymous Hub delivery, Pages delivery and actual-device checks are recorded separately. No complete offline startup, service warranty or automatic compliance with identity-photo rules is promised. |
| |
| This repository has clean file-only history under otama3. The old otama repositories are retained separately and are not active source download dependencies. |
| |
| |
| ## RVM lightweight portrait matting |
| |
| [RVM alpha-only + scalar guided reconstruction](models/rvm-alpha-fgf-e75bfaf9-82cd26c5-v1/README.md) is provided separately with upstream GPL-3.0 code/license notices, artifact changes and corresponding source. Application MIT licensing does not replace model terms; see the bundle card for the pretrained-model license clarification. |
