Web development / browser experiment

A warm-up consumable for PROVENANCE:
one image in, one 2000px proof sheet out.
Image processing stays in the browser. OWLv2 model weights download remotely on first use.

Working artifact

COMPOSITION

PROOF SHEET

The project

A local machine for making visual evidence strange.

Proof Sheet turns an uploaded, dropped, or pasted image into a deliberately official-looking document. It combines image treatment, object-region callouts, poetic misclassification, grain, typography, and a deterministic seed into one repeatable poster flow.

Input
One image, selected locally, dropped, or pasted
Output
Downloadable 2000px PNG proof sheet
Runtime
Client-side TypeScript, Canvas, a Web Worker, Transformers.js, and optional WebGPU/WASM inference
Fallback
Deterministic local geometry when model inference is unavailable

Pipeline

The browser is the studio.

  1. Mask

    A local image is reduced to a working canvas and given a lightweight local background treatment.

  2. Read

    OWLv2 queries visual regions in a worker through WebGPU or WASM, with a deterministic geometry fallback.

  3. Compose

    Dither, callouts, grain, labels, and a seeded barcode are composed into the final proof sheet.

Data boundary

The image stays close.

The selected image is read by the browser and is not uploaded by this tool. The image treatment, dither, composition, and final PNG are produced locally.

Remote request
OWLv2 model weights download from the configured Transformers.js model source on first use.
Local execution
WebGPU or WASM performs inference in a Web Worker when the browser supports it.
Fallback
If the model cannot initialize, the tool returns to deterministic local geometry rather than blocking the composition.
Telemetry
The portfolio code does not intentionally send the selected image to an analytics or application server.
