My research aims to build an editing system for casually-taken photos and videos to enable cinematic focus, perceptual image quality and lighting. My goal is to make casual photos and videos, such as the kind taken by personal devices (e.g. smartphones), an effective and ubiquitous visual storytelling form.
I feel truly fortunate to have collaborated with these inspiring people from the industrial research labs (in chronicle order): David E. Jacobs (Google Research), Jonathan T. Barron (Google Research), Yun-Ta Tsai (Google Research), Vladlen Koltun (Intel), Qifeng Chen (Intel), Kevin Matzen (Facebook), Joon-Young Lee (Adobe), Kalyan Sunkavalli (Adobe) , Zhaowen Wang (Adobe) .

Here are projects I did for fun (or for fun classes).Computer Graphics
In this project, we present a system for cross-domain similarity search that helps us with sketch-based 3D shape retrieval. Instead of using hand crafted features for searching, we propose our DeepSketch neural network that is built upon the Siamese network to learn features for KNN search. Here is a report on this project.
It is well known that cinematographers may carefully select colorsto provoke an emotional response, provide visual clarity, or serve anarrative purpose. We also have the sense, however, that the simple set of colors used in cinema is distinguishable both from the colors of casual videos and among different cinematic genres. In this project, we analyze how color is used in cinema and exploremethods to transfer color between cinematic and casual videos. Here is the video and write-up for this project.
In this project, we built an Android APP for an AR food menu. We place a user-selected food image onto a plate in the real world space with a vision-based estimation of the correct homography. Here is a demo link.
