Collimated Whole Volume Light Scattering in Homogeneous Finite Media (2022)
Journal Article
Velinov, Z., & Mitchell, K. (2023). Collimated Whole Volume Light Scattering in Homogeneous Finite Media. IEEE Transactions on Visualization and Computer Graphics, 29(7), 3145-3157. https://doi.org/10.1109/TVCG.2021.3135764

Crepuscular rays form when light encounters an optically thick or opaque medium which masks out portions of the visible scene. Real-time applications commonly estimate this phenomena by connecting paths between light sources and the camera after a si...

FaceMagic: Real-time Facial Detail Effects on Mobile (2020)
Conference Proceeding
Casas, L., Li, Y., & Mitchell, K. (2020). FaceMagic: Real-time Facial Detail Effects on Mobile. In SA '20: SIGGRAPH Asia 2020 Technical Communications (1-4). https://doi.org/10.1145/3410700.3425429

We present a novel real-time face detail reconstruction method capable of recovering high quality geometry on consumer mobile devices. Our system firstly uses a morphable model and semantic segmentation of facial parts to achieve robust self-calibrat... Read More about FaceMagic: Real-time Facial Detail Effects on Mobile.

Improving VIP viewer Gaze Estimation and Engagement Using Adaptive Dynamic Anamorphosis (2020)
Journal Article
