| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 98 === Block Mode Selection is one new way to improve the performance of distributed video coding (DVC). Since there are many factors influencing the correctness of Block Mode Selection, the decision of block mode is not an easy task. In this thesis, a low complexity Block Mode Selection model is proposed to select the block modes more correctly in the WZ frame. The proposed Block Mode Selection modules can increase the RD performance up to 2.8 dB as compared with the traditional DVC codecs. Moreover, the subjective quality can be improved by using the proposed adaptive deblocking filter, another contribution of this thesis, when the objective quality is kept the same.
