代码说明:

  DCT变换:变换域系数选取采用阈值编码,:阈值越小,图像恢复效果越好,但压缩效果差,一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    工作流系统模型的性能等价分析􀃃 讨论了基于随机Petri网的工作流系统的顺序、并行、选择、循环4种基本模型,并详细推导了这4种基本模型的性能等价公式.最后通过现实中的一个工作流实例来说明如何建立相应的随机Petri网模型,以及如何利用这些性能等价公式来计算工作流的性能参数.给出了定量分析工作流系统性能的通用方法,通过用这些等价公式不仅可以对复杂的系统进行性能等价化简,而且还可以得到性能参数的乘积解.(Workflow Performance Equivalent points)
