本程序利用奇異值分解對3通道彩色圖像進行壓縮分解，具體步驟如下： 壓縮過程： 1. 選取子圖像大小K值，把圖像分解成M×M個子圖像，IMG(s),s=1,2,…, M2，其中M=N/K，原始圖像IMG大小為N×N。 2. 計算這M2個子圖像的平均值average，對每幅子圖像減去均值圖像得到新圖像。 3. 計算相關矩陣R，其元素定義為 。 4. 計算R的特征值與特征向量，計算每幅子圖像與最大特征向量的內積，便得到編碼，即壓縮后的圖像。

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
