-
Currently, transforming coding is one of the most used approach for image coding, where the discrete cosine transform ( dct ), the discrete wavelet transform ( dwt ), and the lapped biorthogonal transform ( lbt ) are widely utilized. how to reduce the complexity of these discrete transforms, is the key technique to image compression. in this thesis, a type of lapped biorthogonal transform which can map integers to integers is considered
變換編碼是圖像壓縮中的主流方法，其採用的主要變換有離散餘弦變換、離散小波變換、雙正交疊式變換，如何減少這些離散變換的計算復雜性，一直是圖像壓縮研究的重要課題。 -
First we give some notations : where r lti : the load of the machine at step t ( i. e., immediately after the ith job has been scheduled ) optt : the current optimum makespan in step t ( for the job set { j1 ; …, jt } ) lbt : the lower bound of the length in step t for a set of jobs with processing times p1, …, pn, there are three straightforward lower bounds for the makespan of any preemptive schedule on m identical machines : max so we have lb = max ( 3. 2. 1 ) the algorithm will schedule jobs in such a way that, at any step t algorithm : a new job jt + 1 ( which arrives at time t + 1 ) is assigned as follows : step 1 compute the new lower bound lbi + 1 according to ( 3. 2. 1 ) step 2 research the following reserved intervals
需加工n個工件人； … ；人，每個工件是在線到達（ oneb ， olle ）且可打斷的，機器人人的準備時間為az ，怎樣安排加工順序，使工件的最大完工時間（ makespan ）盡可能地小，稱此問題為帶機器準備時間的平行機在線排序問題。它是帶機器準備時間的平行機排序和平行機在線排序問題的綜合和推廣；具有廣泛的應用背景。這里工件在線到達（ onebyone ）指的是工件的情況並不是提前知道的，只有將工件jj人安排完以後我們才能知道工jj的一些情況p工件的加工時間p 。 -

Based on the computational structure of the proposed lapped transform, an efficient multiplierless algorithm for the lapped biorthogonal transform ( lbt ), called integer lapped biorthogonal transform ( intlbt ), is proposed
利用提升原理，提出整數離散餘弦變換演算法，以該演算法為基礎設計了新雙正交疊式變換的整數實現演算法，其計算只需要少量的移位和加法運算。
