- W2066800382 abstract "This paper presents an approach to enhance the resolution of refocused images by super resolutionmethods. In plenoptic imaging, we demonstrate that the raw sensor image can be divided to a numberof low-resolution angular images with sub-pixel shifts between each other. The sub-pixel shift, whichdefines the super-resolving ability, is mathematically derived by considering the plenoptic camera asequivalent camera arrays. We implement simulation to demonstrate the imaging process of a plenopticcamera. A high-resolution image is then reconstructed using maximum a posteriori (MAP) superresolution algorithms. Without other degradation effects in simulation, the super resolved imageachieves a resolution as high as predicted by the proposed model. We also build an experimental setupto acquire light fields. With traditional refocusing methods, the image is rendered at a rather lowresolution. In contrast, we implement the super-resolved refocusing methods and recover an image withmore spatial details. To evaluate the performance of the proposed method, we finally compare thereconstructed images using image quality metrics like peak signal to noise ratio (PSNR)." @default.
