An Efficient Algorithm of Gray Projection Cyclostyle Matching to Image Retrieval

This paper presents an improved image retrieval algorithm which based on the gray projection cyclostyle matching to overcome the shortcomings of conventional content-based image retrieval methods. The algorithm based on the analysis that gray scale projection curves of horizontal and vertical direction of the images fully reflects the feature of gray distribution in the corresponding direction, then compares with them if it's not homology. The experimental results show that the presented algorithm can preferably meet the requirements of image retrieval and greatly decrease the amount of calculation.
