TLDR
In this paper, a light field refocusing method was proposed to obtain a super-resolution image from a single image using a series of sub-aperture images captured by a single light field camera.Abstract:
The invention relates to a light field refocusing method, and the method comprises the following steps: initialization: extracting a sub-aperture image corresponding to an image photographed by a light field camera; recording position information: recording the position information of the extracted sub-aperture image of the light field camera; first super-recognition: taking one sub-aperture image according to the sequence, and carrying out the first super-recognition of the sub-aperture image through employing the trained super-recognition method; carrying out the super-recognition of the next sub-aperture image through employing the same method till the super-recognition of the last sub-aperture image is carried out; super-recognition focusing: obtaining a high-resolution refocus through employing the information of the sub-aperture images at the adjacent positions after refocusing conversion, a super-recognition reconfiguration method and a series of sub-aperture images. The multiple of a finally obtained light field camera super-resolution image is much greater than the multiple which can be obtained through a conventional super-recognition method, and greatly improves the resolution of a light field camera image obtained through a conventional method.read more
