Density evolution theory is specified and is applied to the analysis on the threshold of decoding, through which guidance can be provided to optimize irregular ldpc codes
闡述了密度進化理論，並分析了譯碼過程中存在的閾值現象。然後介紹了密度進化理論在ldpc碼優化方面的應用。 -
The method includes split originality image region, filter, separately coding the lowest frequency sub - band coefficient, adaptively setting threshold of different image region, setting up flag matrix, and filtering after decoding to eliminate domino effect of split
這種編碼方法主要包括：對原始圖像進行分塊、濾波；對最低頻子帶系數單獨編碼；對各塊圖像自適應地進行閾值設置；設立標志矩陣；解碼后進行濾波消除分塊效應。 -
Fractal image compression coding ( ficc ) is a new image coding method developed in recent years and has been studied extensively. based on the analyze of conventional fractal coding and decoding, a fractal image coding algorithm based on changeable threshold and creative function is proposed in this paper. new algorithm is to be in accordance with the feature of human visual system
本文通過對傳統分形圖像壓縮編解碼的分析，提出了門限變化和生成函數改進的編碼演算法，此演算法在一定程度上與人類視覺系統特性相符，我們在理論上證明了在相同的條件下，用改進的生成函數恢復的圖像在質量方面比傳統的生成函數要好，恢復圖像的信噪比有所提高。
