Personal projects

High-Resolution Image Compositor

2025 - present

Super-resolution imaging built for iPhone telephoto stacks.

  • Aligns multiple telephoto frames to a wide-angle base using SIFT.
  • Blends multi-frame data for ultra-detailed, panorama-like composites.
  • Ships with a real time preview system for responsive capture.
  • Designed as a modular pipeline so each stage can be swapped, profiled, and improved independently.
