About Me | |
I am a software engineer at Google, focusing on mobile computational photography. I obtained my BS degree in 2004 and defended my PhD dissertation in 2008, both at National Taiwan University. My research interests include computational photography, image/video processing, computer vision, and hardware architecture: basically anything that records, reads, modifies, writes, or displays the pixel, voxel, or ray-el values. See my Curriculum Vitae and Google Scholar profile about my professional work. |
