To measure the influence of depth estimation error on depth coding and virtual view rendering in a free-viewpoint television (FTV) system, a multi-view depth estimation is proposed to solve the problem for coding and view synthesis. Firstly, the consistency of initial depth is checked and the influence of initial miss-matches is minimized by introducing an additional adaptive matching error that penalizes the unreliable matches. Then according to specific criteria, the multi-reference depth maps are merged into one disparity map to improve the quality of disparity map. Finally, a multi-lateral filtering is used to preserve details in the depth map and simultaneously smooth the depths in occluded areas at object boundary, less texture and discontinuity regions. Experimental results show a significant improvement of the initial input depth maps and coding efficiency, as well as a reduction of view synthesis artifacts.

This paper describe the relationship between C++ templates and partial evaluation. In C++, templates were designed to support generic programming, but not deliberately provided the ability to perform compile‐time computations and code generation. These features are completely deliberate, and as a result their syntax is ill at ease. After a review, these features in terms of partial evaluation, a much simpler syntax can be achieved. In C++, it may be regarded as a two‐level language in which types are first‐class values. Template instantiation resembles an offline partial assessor. In this paper, we explain groundwork in the direction of a single mechanism based on Partial Evaluation which unifies generic programming, compile‐time computation and code generation. The language Catat is introduced to demonstrate these ideas.
In the present work we studied the fabrication of ferroelectric film as PLZT by the sol-gel technique, and the birefringence optical property induced by the external voltage is measured by the electro-optic modulated ...
