Necktie pattern retrieval method based on image edge characteristics

In order to increase the accuracy and speed of necktie pattern retrieval,an image retrieval method based on the edge characteristics is introduced. Firstly,the edge of necktie pattern is extracted by edge detection,and the result is quantized as edge characteristic. After that,the statistic of the edge characteristic distribution is analyzed. Based on the analyses,the necktie pattern is divided into stripe,polygon and complex pattern. Finally,the pattern to be retrieved is matched with the patterns in the database,and the most-similar patterns are chosen as a result. The experiment result shows that the proposed method could retrieve similar patterns precisely with low computation, which is greatly practicable.
