Sheet Music Watermark Removal & Upscale

STAR Summary

Situation

I needed clean, readable sheet music. Most of what I could find was low-res and watermarked.

Task

Create a workflow that removes watermarks and upscales sheet-music scans while keeping notation readable.

Action

• Trained a UNet model on paired page images for watermark removal.
• Upscaled low-resolution scans (e.g., ~612x792) to print-friendly resolution (e.g., ~1700x2200) with Very Deep Super-Resolution (VDSR).
• Wrapped it in a simple GUI so I could run the full pipeline.

Result

• Typical runs produce cleaner, more readable output in seconds per page (hardware- and batch-dependent).
