OpenRefocus

In order to observe targets in expanded depths of view in light field imaging, we design an open source light field parallel refocusing GUI software named OpenRefocus, which is based on classical spatial projection integration. OpenRefocus consists of four-tier MVC-style separation framework including presentation layer for display and interaction, core processing layer for light field refocusing, data acquisition layer for input and output, and security monitoring layer for exception monitor. Moreover, OpenRefocus adopts Qt-based multi-threaded asynchronous processing architecture to improve the resource utilization rates of both CPU and system, and it is also equipped with CUDA-based distributed parallel computing architecture aiming at significantly accelerating the light field refocusing speed. OpenRefocus supports GUI in Windows platform, and it is a code-free software for users.
