Unity Photo-to-Coloring Prototype

I’m building a mobile coloring game and need an offline Unity prototype that can take either a photograph or a hand-drawn illustration and return a pristine coloring-book page: pure white background, crisp black outlines, no stray artefacts. This goes well beyond a novelty filter—the output has to feel like something you could print and hand to a child with crayons.

What I expect the prototype to do
• Run inside a lightweight Unity scene (C#) and work entirely offline on device.
• Ingest a standard image file, apply a reliable pipeline of edge detection, noise removal, and contrast adjustment, and deliver a flattened PNG or texture ready for in-game coloring.
• Lean on the OpenCV-for-Unity plugin if that’s your preferred toolkit, yet I’m open to alternative libraries or custom shaders if you can achieve the same quality.

Where you can really shine
Show me previous work demonstrating similar image-processing challenges—especially anything that proves you can turn messy, real-world input into clean vector-style or line-art output. If you already have snippets or demos that highlight robust edge detection or noise reduction, link them in your bid.

Next steps
I’ll test the delivered Unity package on several sample photos and scans, verify the clarity of the outlines, and confirm the process holds up without an internet connection. If the prototype meets the mark, we can extend it into region-based flood-fill and additional game features.

Let’s make a coloring page engine that actually feels professional.
