| Research Abstract |
For advanced three-dimensional visual media, arrays of multiple cameras are used to capture light fields from scenes. However, such multi-dimensional light fields are composed of enormous data. In this research, a method for efficient light field compression is proposed using three-dimensional multi-focus images synthesized from four-dimensional light fields. The method gains good quality over 30dB even when the compression ratio is 1/1000, where the conventional method using disparity compensation suffers from awful degradation of reconstructed images. The research papers received two Best Paper Awards and have been published in the top conferences and journals of image processing. The proposed method will be extended to deal with not only light fields composed of multi-view images but also light field video.
