Researcher

Changchang Wu

Also known as C. Wu

Changchang Wu is a computer vision researcher whose work connects structure-from-motion software with generative 3D product views. He completed a 2010 Ph.D. focused on geometry-driven feature detection and helped develop multicore bundle adjustment for large 3D reconstructions. His single-author 2013 paper pursued linear-time structure from motion; in 2018, VisualSFM earned the PAMI Mark Everingham Prize, and he authored a Google guide to VR180. As of October 2026, he is affiliated with Google LLC in AI and image processing; in 2025, he contributed to generative AI for shoppable 3D product views from a few images.

Timeline

  1. 2010

    A computer vision doctorate

    He completes a Ph.D. focused on geometry-driven feature detection in 2010.

  2. 2011

    Multicore bundle adjustment

    He and Sameer Agarwal, Brian Curless, and Steven M. Seitz publish Multicore Bundle Adjustment at CVPR in 2011. The system uses multicore CPUs and GPUs to solve large-scale 3D scene reconstruction problems.

  3. 2013

    Linear-time structure from motion

    He presents a single-author paper, Towards Linear-time Incremental Structure from Motion, at 3DV in 2013; the conference program lists his affiliation as Google.

  4. 2018

    The PAMI Mark Everingham Prize

    He receives the PAMI Mark Everingham Prize for VisualSFM in 2018; its citation recognizes the software library's contribution to Structure from Motion.

  5. 2018

    Engineering for VR180

    He authors Google's VR180 publishing guide as a software engineer in 2018. It explains the format's video metadata standard.

  6. May 2025

    Generative 3D product views

    In May 2025, he contributes to Google's generative AI techniques for shoppable 3D product visualizations from as few as three product images.

  7. As of October 2026

    AI and image processing at Google

    As of October 2026, he is affiliated with Google LLC in AI and image processing.
