decimen optical transfer

We have hosted the application decimen optical transfer in order to run this application in our online workstations with Wine or directly.

Quick description about decimen optical transfer:

Decimen Optical Transfer is a browser-based proof of concept for moving files between devices through animated QR codes. A sending screen continuously displays encoded frames while a receiving camera captures enough of them to reconstruct the original payload. The system requires no direct network path, pairing process, native application, or permission beyond camera access. Fountain coding makes the stream tolerant of missed, blurred, duplicated, and out-of-order frames without requesting retransmission. Each QR frame includes session and file metadata, allowing a receiver to join an active stream or reset when a new session begins. QR decoding runs through zxing-cpp compiled to WebAssembly and uses workers to process camera frames efficiently. Configurable settings control payload size, transmission speed, QR density, capture resolution, and worker count, while a final hash verifies the recovered file.

Features:

• Screen-to-camera file transmission
• Animated fountain-coded QR streams
• Dropped and out-of-order frame tolerance
• WebAssembly-based QR decoding
• Configurable transfer and camera settings
• Hash-based file integrity verification

Programming Language: TypeScript.
