Light-Field Rendering in the View Interpolation Region without Dense Light-Field Reconstruction

Abstract

Different scenes according to a user's movement are important to provide a real three-dimensional (3D) experiment. The different scenes, called virtual viewpoint images, can be rendered by 3D structures. However, 3D structure reconstruction from camera images requires high computational complexity and computation time. A light-field rendering algorithm uses the light fields captured by the camera array as the input and selects the light rays for the virtual viewpoint image. Herein, a light-field rendering algorithm in the view interpolation region using line interpolation is introduced. The proposed algorithm functions well to generate planar viewpoint images and zoomed in/out viewpoint images. © Published under licence by IOP Publishing Ltd.
