本文的主要成果有:提出了一種混沌實值序列的生成方法，並在此基礎上引入模變換對語音信號進行加密，經實驗模擬可以得到良好的加密效果;對零動態可逆混沌語音加密通用模型的一個具體加密演算法進行了改進，並通過模擬實驗比較了改進前後演算法的加密性能。The sequences are transformed to a relative sequence, in which all the segments are normalized by the previous segment. the relative sequences are categorized and indexed by suffix tree, and the result of the suffix tree search is the potential similar subsequences
通過將序列變換為相對序列，實現了對序列中任意位置、任意長度子序列的規范化；為了提高查詢效率，將相對序列的特徵向量進行離散化分類，並使用后綴樹進行索引。Because of the high space correlation among four descriptions, the coding method is very robust but unpractical. in this paper, a new multiple description video coding algorithm, called prediction - based spatial polyphase transform ( pspt ) multiple description video coding, is proposed to promote the error resilient ability and reduce the computational complexity of the h. 264 coder
本文在空間多相變換基礎上引入子序列間的預測，提出了一種新的基於h . 264的多描述視頻編碼演算法? ?基於子序列間預測的空間多相變換多描述視頻編碼，提高了空間多相變換多描述編碼的效率。Because the method uses the linear measurable function of bearings varying with time, so it is more effective than the normal method which based on bearings of the target directly, and at the same time it can overcome the limits when use the normal method in special situation
由於該方法將目標方位隨時間變化的非線性關系轉換到另一空間的線性關系，這使得檢測更加有效、直觀，並且能夠克服直接採用方位序列檢測目標轉向機動在特殊情況下失效的限制。One of the common characters between traditional algorithms based on dct image coding is that regardless of the content of the image, they use a fixed size block to process, for example, jpeg, mpeg - 1 / 2, h. 263 use constant 8 * 8 block mode. the main work of this article is to propose a sequence images compression algorithm that is based on adaptive block dividing and object to the disadvantages of the one based on fixed - size block dividing. the proposed algorithm is an image compression method, which can auto - adjust dct block size ( 8 * 8 or 4 * 4 ) according to the difference of corresponding blocks between two frames of the sequential image and doesn ’ t process any unnecessary data blocks in order to enhance coding efficiency
傳統的基於dct的圖像編碼演算法的一個共同特點就是:不管圖像的具體內容，採用固定的塊尺寸進行統一的處理，例如jpeg ， mpeg - 1 / 2 ， h . 263均採用固定的8 8分塊方式，本文的重點工作是針對這些採用固定的塊尺寸進行統一處理的演算法的一些缺點，提出了一種基於自適應分塊的序列圖像壓縮演算法，該演算法是一種根據序列圖像兩幀間對應塊的差別自動調整dct變換尺寸（ 8 8或4 4 ） ，對不必要的數據塊不進行處理，以提高編碼效率的序列圖像壓縮編碼方法，具有較高的編碼效率和較好的壓縮效果，與傳統的採用8 8固定分塊方式的壓縮編碼演算法相比，性能有較大幅度的提高，在文中，作者對兩者的壓縮編碼性能進行了分析比較。分享友人
