Abstract

Abstract: Digital refocusing is one of the important properties of light field imaging, and the analysis of its performance has important reference value for the study of light field imaging. In this paper,two different digital refocusing algorithms based on the microlens array light field camera (LFC) in spatial and frequency domain are presented. We study the influences of different domains, interpolation methods and sample radius in digital refocusing algorithm on image quality and computation speed. And we yield a tradeoff between image quality and time consumption in two domains. Experiment results suggest that the two algorithms can achieve digital refocusing with fine image quality and less time consumption.
