Abstract
This paper presents a computational integral imaging (CII) technique based on a unidirectional reconstruction to provide perspective plane images of three-dimensional (3D) objects for occluded object recognition and visualization. CII has been widely investigated for 3D passive imaging systems. However, the conventional CII method provides only front-view plane images along the z axis. In this paper, we propose a new computational method to reconstruct perspective-view plane images of 3D objects. We introduce unidirectional elemental images extracted from original elemental images. The unidirectional elemental images produced by our method with respect to an observation angle are utilized to reconstruct various perspective plane images. Experimental results indicate the efficacy of the proposed method. Also, the proposed method is performed fast due to the nature of the unidirectional processing.
