ENHANCED COMPUTATIONAL INTEGRAL IMAGING RECONSTRUCTION TECHNIQUE BASED ON INTERPOLATION METHOD USING FPGA

摘要

In this paper, a hardware implementation for enhanced computational integral imaging reconstruction (CIIR) technique is proposed. The reconstruction technique is based on image interpolation algorithms to improve the quality of 3D reconstructed images. In the conventional CIIR, the quality of reconstructed output image is degraded due to only a single pixel from each elemental image is used in the reconstruction process. The proposed CIIR method generates new pixels between the original pixels of elemental images using interpolation technique. The interpolated pixels enhance the resolution of the reconstructed image. The proposed hardware exploits both of the concurrent processing and memory organization features, which are available in field-programmable gate array (FPGA) device to achieve several computational operations at real time. To show the feasibility of the proposed scheme, some experiments were carried out, its result exposes that the hardware is able to process digital reconstruction at real time rate with low power consumption.
