From Image Sequence to Mosaic Image

摘要

A 3D plenoptic function in the form of a mosaic image is presented in this paper. A sequence of plane images and relative cylinder panoramas are sampled originally by a camera constrained on a line. Then, these original images are arranged into a mosaic image by abstracting appropriate circles from the images and pasting them together. Pixels in the mosaic image are indexed in three parameters: camera location along the track line and two angles θ and Φ. When rendering a novel view from a certain camera location, pixels in the view are mapped into view-rays of parameters θ and Φ. Then, the values of view-rays are indexed from the mosaic image. Experimental results show that the proposed method is effective in rendering scene.
