碩士 === 國立成功大學 === 電機工程學系碩博士班 === 99 === The thesis proposed a motion compensated infinite impulse response filters algorithm for depth maps in 3D video system. The filter is used for post-processing of depth maps. If inappropriate depth maps are used to render stereo image pairs, the view of rendered image would flicker and become difficult to be converged by human’s eyes. Our proposed filter can be adopted to filter depth maps so as to relief the uncomfortable visual effect when human’s eye is focusing on the rendered image pair. Our proposed algorithm contains calculation of motion magnitude, and the coefficient of our filter is adaptive to motion magnitude to be applicable in different scene. The result shows that the visual quality of rendered image pair is improved after the used depth maps are post-processed by our proposed algorithm. The thesis also proposed architecture design of our algorithm. Following the top-down design flow methodology, we expand the design space, extract architectural information and explore from top to lower levels of abstraction. By the systemic approach, the optimal solution which meets the specification we explored in design space will mapped to our architecture design.
