Real-time per-pixel focusing method for light field rendering

Abstract Light field rendering is an image-based method that does not use 3D models but only images of the scene as input to render new views. approximation, represented a set images, suffers from so-called refocusing artifacts due different depth values pixels in scene. Without information about depths scene, proper focusing light limited single distance. The correct addressed this work and real-time solution proposed for scenes, based on statistical analysis pixel contributing final image. Unlike existing techniques, need precomputed or acquired information. Memory requirements streaming bandwidth are reduced possible even high resolution data, yielding visually satisfactory results. Experimental evaluation method, implemented GPU, presented paper.
