Personalized Restoration via Dual-Pivot Tuning

no code implementations28 Dec 2023 Pradyumna Chari, Sizhuo Ma, Daniil Ostashev, Achuta Kadambi, Gurunandan Krishnan, Jian Wang, Kfir Aberman

This approach ensures that personalization does not interfere with the restoration process, resulting in a natural appearance with high fidelity to the person's identity and the attributes of the degraded image.

no code implementations18 Apr 2023 Ellin Q. Zhao, Alexander Vilesov, Shreeram Athreya, Pradyumna Chari, Jeanette Merlos, Kendall Millett, Nia St. Cyr, Laleh Jalilian, Achuta Kadambi

Existing device manufacturers recommend that a subject who has been outdoors in sun re-acclimate to an indoor environment after a waiting period.

MIME: Minority Inclusion for Majority Group Enhancement of AI Performance

no code implementations1 Sep 2022 Pradyumna Chari, Yunhao Ba, Shreeram Athreya, Achuta Kadambi

A common misconception is that minority inclusion does not increase performance for majority groups alone.

Synthetic Generation of Face Videos With Plethysmograph Physiology

no code implementations CVPR 2022 Zhen Wang, Yunhao Ba, Pradyumna Chari, Oyku Deniz Bozkurt, Gianna Brown, Parth Patwa, Niranjan Vaddi, Laleh Jalilian, Achuta Kadambi

Accelerated by telemedicine, advances in Remote Photoplethysmography (rPPG) are beginning to offer a viable path toward non-contact physiological measurement.
