摘要
The present invention relates to an image indexing and retrieval method using the rosette pattern for the improvement of retrieval efficiency and performance, comprising the steps of: (a) defining a rosette pattern corresponding to the size of a subject image from which information will be extracted; (b) extracting information from the said subject image using the rosette pattern defined in the said step (a); (c) storing the information extracted in the said step (b) into a memory; (d) if a user provides a query image for information retrieval, repeating the said steps (a) and (b) with respect to the said query image; and (e) calculating the similarity between the information stored in the said step (c) and the query image information extracted in the said step (d), and conducting the retrieval using the calculated similarity. ;The present invention's method has a merit in that image information may be stored and retrieved effectively through the rosette pattern, even with a small number of pixels. Furthermore, the retrieval efficiency achieved in the present invention is higher than the efficiency of the conventional histogram distribution methods. Additionally, because fewer pixels are used, the memory space required for the indexing may be reduced significantly.
