本程序利用奇异值分解对3通道彩色图像进行压缩分解，具体步骤如下： 压缩过程： 1. 选取子图像大小K值，把图像分解成M×M个子图像，IMG(s),s=1,2,…, M2，其中M=N/K，原始图像IMG大小为N×N。 2. 计算这M2个子图像的平均值average，对每幅子图像减去均值图像得到新图像。 3. 计算相关矩阵R，其元素定义为 。 4. 计算R的特征 ...

Produce Java classes to calculate and display the Poisson probability when input the value of the average (A) arrival rate of customers at some business in the range of 1 to 10. The error message will output when A is out of the range。

zlibyou can found an optimized version of Zlib 1.1.4 that you can embed into every Delphi executable without use external dlls. Further I have build a little example hoping to aid "young" Delphi programmers getting in trouble with streams... Please let me know if you ll discover errors. These obje ...

full wave rectifierDuring the period from 伪 to 蟺, the input voltage vs input current is are positive and the power flows from supply to the load. The converter is said to be operated at rectification mode .During the period from 蟺 to 蟺+伪 , the input voltage vs is negative and the input current ...

Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Jav ...
