次級有效高壓In this paper, two important modifications in dct - based coding algorithm are suggested after making deep study on the generally used scheme of h. 263 coder. first, we find plenty of invalid computation in the transformation part of the h. 263 coder and an improved scheme based on the pre - transform decision to avoid invalid computation is proposed. second, in the motion estimation part of the coder, we find that normal search algorithms are not effective, which neglects different levels of motion in image sequences, and we suggest a new search algorithm which has variable search region based on the difference of motion level. combining the pre - transform decision scheme with variable search region method in motion estimation, a global decision coding scheme is provided, which greatly increases the coding speed of h. 263 coder
本文對h . 263編碼演算法的現有實現方法作了深入的分析,首先發現變換部分存在大量無效運算,提出了在變換前加判決的前變換判決的編碼方案,以壓縮無效的變換運算;其次發現運動估計部分由於忽略了圖像場景的分級運動而存在一定的無效搜索運算,提出了基於分級運動的可變搜索域法來壓縮無效的搜索運算;最後將前變換判決方案與運動估計的可變搜索域法有機地結合在一起,提出了全局判決編碼方案,從而比較全面地改進了現有實現方法,因而能大幅度地提高編碼器的編碼速度General compressing technologies are not proper in some circumstances for the receivers are always required to decompress the data completely to manupulate the original data ( querying, validating etc. ). the embedded document structure of xml also makes it difficult to perform access control because the traditional file level access control systems could not fulfill the requirement of element or attribute level access control. in the paper we first present a scheme for xml - based data exchange which is an xpath - query - friendly compressor for xml
壓縮技術是提高交換效率的一種方法,但接收方需要對壓縮文檔完全解壓才能夠執行進一步的操作,在很多應用中這種方式並不適用,這就提出了如何在高效壓縮的同時在壓縮后的xml文檔上進行查詢等操作的問題;另一方面,由於xml文檔的層次結構的特殊性,傳統的文件級別的訪問控制已經不能適應在元素、屬性的級別上進行訪問控制的需要,所以對只需要訪問部分xml文檔內容的用戶進行有效的數據訪問控制也是xml數據訪問控制面臨的一個問題。
