  1. Most of these standards are based on the method of inter - frame motion compensation and two - dimensional discrete cosine transform ( 2d - dct ) and encode and describe the color video in ycbcr 4 : 2 : 0 format, which want to take advantage of human visual system ( hvs ) to save bit expense by decreasing the resolution of two color difference components

    當前國際上的壓縮標準普遍採用運動補償加內二維離散餘弦方法,並且將彩色視頻序列表示為ycbcr格式,試圖利用人眼的視覺特性降低對色差信號的解析度來節省比特開銷。
  2. 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對應塊的差別自動調整dct尺寸( 8 8或4 4 ) ,對不必要的數據塊不進行處理,以提高效率的序列圖像壓縮方法,具有較高的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,作者對兩者的壓縮性能進行了分析比較。
  3. This thesis is part of the project of national science foundation of china “ study on color video coding based on four - dimensional matrix ”. a multi - matrix theory model has been established in the project. and the color video is presented into a four dimensional matrix model and the four - dimensional discrete cosine transform ( 4d - mdct ) is applied to reduce the correlation between color components and adjacent pixels

    將多個彩色視頻構建在一個四維矩陣模型中進行運動補償預測、四維矩陣離散餘弦和矩陣量化,最後利用基於上下文的方法進行壓縮,以全面去除彩色視頻各象素之、各彩色分量之以及連續的相關性,從而實現高信噪比條件下的高倍壓縮。
