Three-Dimensional Image Security System Combines the Use of Smart Mapping Algorithm and Fibonacci Transformation Technique

Abstract

In this paper, a three-dimensional (3D) image security system combines the use of the smart pixel mapping (SPM)algorithm and the Fibonacci transformation technique is proposed. In order to reconstruct orthoscopic 3D images withimproved image quality, a smart pixel mapping process is adopted. Based on the SPM-based computational integralimaging (CII) system, the depth-converted elemental image array (EIA) is obtained for increasing the quality of thereconstructed image. In the encryption process, the depth-converted EIA is scrambled by the Fibonacci transformation(FT) algorithm. Meanwhile, the computational integral imaging reconstruction (CIIR) technique is used to reconstructthe 3D image in the image reconstruction process. Compared with conventional CII-based 3D image encryptionmethods, the proposed method enable us to reconstruct high-resolution orthoscopic 3D images at long distance. Todemonstrate the effectiveness of the proposed method, some numerical experiments are made to test the validity andthe capability of the proposed 3D image security system.
