This algorithm makes use of a principle of dynamic updating connecting itemsets against the item increasing in n set of frequent itemsets to obtain any frequent itemsets and though researches and analyses,it can be seen that this algorithm will get all frequent itemsets by scanning database only once.

Study of infrared weak small target enhancement methods based on image fusion

A novel scheme of target enhancement in high-resolution polarimetric SAR imagery is proposed in this paper,which is based on the target s polarization orientation angle feature.

Essentially, image fusion has the function of image enhancement, so this paper proposed a weak small target enhancement method based on image fusion.

To solve the NP-complete no-wait flowshop problems,objective increment properties are analyzed and proved for fundamental operations of heuristics.

Besides investigating the crowding distance and the elitist solution strategy,two effective bi-criteria local search procedures based on objective increments are presented to improve searching effectiveness.

Different from traditional methods in which objectives are completely computed for a new generated schedule,objective increment methods are presented in this paper.
