Distributed Video Coding with Majority Rule on Multiple Sets of Side Information
نویسندگان
چکیده
This paper proposes a method for retrieving the original information X out of multiple sets of side information (SI) such as Y1, Y2, Y3, etc. These sets are generated using key frames that are encoded by a conventional video codec. By using the method of majority rule, the most reliable bits from the decoded Yi’s are selected for the composition of Y∞, the conditional entropy H(X|Y∞) of which becomes much lower than any individual conditional entropy H(X|Yi). The method is demonstrated using 3 typical image sequences with different characteristics.

متن کاملOn Mining Fuzzy Classification Rules for Imbalanced Data
Fuzzy rule-based classification system (FRBCS) is a popular machine learning technique for classification purposes. One of the major issues when applying it on imbalanced data sets is its biased to the majority class, such that, it performs poorly in respect to the minority class. However many cases the minority classes are more important than the majority ones. In this paper, we have extended ...
