Propagation Algorithm for Image-Based Rendering Using Full or Partial Depth Information
نویسنده
چکیده
We propose a new approach, called the Propagation Algorithm, for the image-based rendering (IBR) application that synthesizes novel images, as taken by virtual cameras at arbitrary viewpoints, using a set of acquired images. The Propagation Algorithm proactively propagates all available information from actual cameras to virtual cameras, using the depth information at all or some of intensity pixels. This process turns the IBR problem into a two-dimensional interpolation problem at virtual image planes. Each virtual image thus can be efficiently rendered at once for all image pixels. Experimental results show the Propagation Algorithm produces accurate rendering, even around object boundaries – where most of the existing IBR techniques fail.

Segmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...
متن کاملThree - Dimensional Propagation Algorithm
Depth image based rendering (DIBR) is the process of synthesizing new “virtual” views from a set of “real” views which include color and depth images. Because of its photorealism and less stringent computational requirement, DIBR has many applications such as 3D TV, remote reality, and video conferencing, and has become one of the hot research areas in visual computing in recent years. Since th...

This paper proposes a new 3D propagation algorithm for the depth image-based rendering problem with multiple color and range cameras at arbitrary positions. The proposed algorithm efficiently renders novel images at arbitrary virtual views by propagating all available depth information from range cameras to color cameras, and then all available depth and color information from color cameras to ...
