摘要
A method of searching for images in a database system determines weights of desired image features by taking into consideration both recent user relevance feedback information and whole feedback information. The method is performed in accordance with a multimedia data structure which reflects user feedback change. According to one embodiment, the data structure includes information describing the features of a specific image, recent user feedback information when the weights of the features of the specific image are learned and determined by the user relevance feedback information, and whole feedback information when th weight of the features of the specific image are learned and determined by the user relevance feedback information. The weights of the image features are determined considering both the recent user feedback information and the whole feedback information, and the image features according to the determined weights are used for the image search.
