Aiming at the problem of rapid retrieval in large scale image,two methods:exhaustive filtration and non-exhaustive filtration are proposed to filter query results for inverted indexing structure-based retrieval methods.The objective is to improve query efficiency without influencing accuracy.Exhaustive filtration constructs a hyper-sphere whose center is the query feature,and the corresponding radius is calculated adaptively.Only the features that lie in the hyper-sphere are used to sort,then the number of ...
