Summary
👤
Senior🎓
Top SchoolLex Song is an independent machine learning researcher with over a decade of hands-on experience in computer vision, video tracking, and face image processing, spanning synthesis, analysis, expression transfer, and identity swapping. He combines deep-learning prototyping with production-ready C and modern C++ engineering, plus Python scientific stack expertise and cross-language integration. Previously a senior ML scientist at Digital Domain, he led projects in TTS-driven facial animation and 3D face reconstruction, and earlier improved VR tracking algorithms at HTC Vive. Comfortable across problem domains and platforms, he’s also reverse-engineered geospatial tiling logic for an open-source project mapping Google’s 3D satellite mode—an example of his curiosity for low-level systems as well as high-level models. Based in Taipei, he’s known for rapid adaptation and turning novel algorithms into practical demos and tools.

Reversing Google's 3D satellite mode
Role in this project:
Back-end Developer
Back-end DeveloperContributions:9 commits, 3 PRs, 21 comments in 1 year 2 months
Contributions summary:Lex primarily worked on reverse engineering Google's 3D satellite mode. They implemented the `lat_long_to_octant.js` file, which translates latitude and longitude coordinates into octant values for efficient data retrieval. The user also added the logic to search for octants based on lat/long coordinates by modifying and adding functions to find the relevant geographical data. This involved refactoring and rewriting existing code and integrating functions from other parts of the project to optimize the process.
