Abstract
In this work, a framework relying on image-based rendering is presented for
synthesizing intermediate views in the forward transition of two uncalibrated images
without using explicit geometry information. First, the source and destination images are partitioned into regions. Each region is a presentation of the scene surface which
can be approximated by a plane. To generate the intermediate views during the transition, each region is morphed according to its warping function individually. The warping function adopted here is derived from homography. Homography is estimated by using the corresponding feature points found by SIFT in the source and destination images. The morphed regions are combined to generate the intermediate image at a specific moment. Then the sequence of synthesized intermediate views can be played successively to produce smooth view hopping. Each morphed image can be further improved by zoom-blurring. Taking advantage of visual effect by zoom-blurring, the whole sequence of intermediate views would be more absorbing. We also introduce painting styles provided by non-photorealistic rendering, so that view hopping with artistic styles is also available in our framework.
