First,to get rid of the repeated part between ordinal border upon images,image joint algorithm is adopted,and then,use a series of pretreating methods,such as gray transformation and image smoothing,to take off the yawp,segment the image with gray image binary transformation based on the minimum error method,by th.

A novel hierarchical Mumford-Shah functional model is addressed to simultaneously segment, denoise and reconstruct the data within a given vector-valued image such as a color image, and to handle important image features such as triple points and other multiple junctions, which can be seen as a hierarchical case of the Mumford-Shah minimal partition problem for vector-valued images.

The main factors causing the failure of power communication system can be determined by qualitative analysis in which the minimal cut set analysis(MCSA) is used.

The system risk is analyzed based on the minimum cut sets which are solved using the Semanderes algorithm.

The minimum cut sets(fault spectrums) are obtained by qualitative analysis.

Qualitative analysis and quantitative analysis are made by using of fault tree analysis,minimum cut sets and importance are calculated.

All of minimum cut sets of fault trees are found out and the qualitative analysis .

Introduces a new simulation method based on the minimum cut sets of fault tree, analyzes the way using the method in the research of the reliability of FMS, a case is presented to prove its correctness.
