image_compress
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的特征值与特征向量,计算每幅子图像与最大特征向量的内积,便得到编码,即压缩后的图像。
(This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.)

蒙特卡洛模拟法是当系统中各个单元的可靠性特征量已知,但系统的可靠性过于复杂,难以建立可靠性预计的精确数学模型或模型太复杂而不便应用则可用随机模拟法近似计算出系统可靠性的预计值。随着模拟次数的增多,其预计精度也逐渐增高。由于需要大量反复的计算,一般均用计算机来完成。本文件用来求解医院排队论问题(Monte Carlo simulation when the system reliability characteristics of each unit volume is known, but the reliability of the system is too complicated, difficult to establish accurate mathematical model of reliability prediction models are too complex or inconvenient applications are available stochastic simulation method to approximate calculation the expected value of system reliability. With the increase in simulation times, which is expected to gradually increase precision. As the need for a large number of repeated calculations, generally using the computer to complete.
