These implied that the former may take place mainly at the encoding phase and the latter at the maintaining one 可見,關聯性錯誤記憶可能主要發生在編碼階段,而誤導性錯誤記憶則可能主要發生在保持階段。
Then this quadrature is used to classifying the blocks in the encoding phase , resulting in a great reduction to number of domain blocks to search for , hence shortening the encoding time dramatically 在分形編碼時,用該不變量來對圖像塊進行分類,極大地減少了編碼時定義域塊的搜索數目,達到了加速編碼的目的。
Then the fractal dimension can be used to classifying the blocks in the encoding phase , resulting in a great reduction to number of domain blocks to search for , hence shortening the encoding time dramatically 在分形編碼時,用這個維數值來對圖像塊進行分類,大大減少了編碼時定義域塊的搜索數目,達到了加速編碼的目的。
As technologies of various level software reuse , code component , design pattern and analysis pattern provide the means of software reuse in the encoding phase , design phase and design phase of the software life - cycle 摘要代碼構件、設計模式和分析模式是不同層次的軟件復用技術,提供了軟件開發從分析、設計到編碼各階段的復用手段。
However , there ' s a especially unsatisfying problem in this method : too long encoding time , mainly because of the considerable number of domain blocks to compare with for each range block in encoding phase , which , in fact , prevent fractal image compression from becoming a practical method for image compression , hence fast encoding has become a hot issue in fractal image compression 但是,這種方法存在一個最大的問題:編碼時間過長,主要是因為編碼時定義域塊的搜索量非常可觀。這實際上已成為了該方法走向高效能實用化的最主要障礙,因此分形編碼加速方法已成為了近些年來分形壓縮的一個研究熱點。
