To reduce invalid rules in mining association rules, we have analyzed the reasons and presented to add the effect or the relative confidence in the judgment criteria.

First,binary texture matrixes of horizontal and vertical direction were constructed in the template and target image,and then the prime matching result of the two directions was calculated according to the Alogical XOR logical operation in bytes and the final target correlation credibility was obtained by proportion .

By taking account of the number of 1-hop neighboring nodes,the node position accuracy and the ranging errors,we introduce concepts of node relative localization error and relative reliability,and then propose a robust node localization algorithm based on distributed weighted-multidimensional scaling.
