Searching Graphics Based on Feature Points

Abstract: This paper deals with the graphics searching method based on limited feature points. Instead of focusing on the relationship among the graphic elements, the feature points are selected to describe the graphics. All the feature points are uniquely determined by using of the distance between the feature point and datum point and the angle between the datum vector and the feature vector. Based on the analysis of those data, a method is provided for searching the most approximate feature points. The data are computed and integrated, and the numerical characteristic of the graphics is searched. Experiments show that the graphics searching method is valid.#br# Key words: searching graphic; approximate feature point; numerical characteristic; feature vector
