Driver-level AI frame generation

Core contributor to a driver-based AI frame generation path that infers an additional frame between rendered frames. The work focuses on making smoother gameplay available to compatible DirectX 11/12 games even when the game does not integrate DLSS Frame Generation directly.

DLSS 4

Real-time graphics acceleration

Research and engineering around DLSS 4 Multi Frame Generation, where AI-generated frames must fit within a few milliseconds while preserving temporal stability. The work sits at the intersection of frame interpolation, optical-flow signals, GPU scheduling, and image-quality evaluation for real-time games.

Compressed Video Enhancement preview

Compressed Video Enhancement

Research on partition-aware post-processing and deblocking for HEVC compressed videos. The work improved reconstructed video quality, achieved about 10% bitrate saving at similar quality, and led to ICIP 2019 / IEEE TMM publications.
