LIFLET: Light Field Live with Thousands of Lenslets

In this project, we have investigated and realized a system for real-time free-viewpoint image synthesis, which we call LIFLET. We focused on the combination of optical design of 3D photography and software algorithm of photo-realistic computer graphics. We started from an array of lenslets and clarified its characteristics in frequency domain. Then we proposed an algorithm for real-time pixel-by-pixel depth estimation method for higher quality of image synthesis, and employed a dual lens-array system for suppressing optical blurring effect. Finally, we can handle 3D scenes in motion for real-time free-viewpoint contents.
