Abstract

Real-time light field reconstruction for defocus blur may be used to handle the case of simultaneous defocus and motion blur. By carefully introducing a few approximations, a very efficient sheared reconstruction filter is derived, which produces high quality images even for a very low number of input samples in some embodiments. The algorithm may be temporally robust, and is about two orders of magnitude faster than previous work, making it suitable for both real-time rendering and as a post-processing pass for high quality rendering in some embodiments.
