    摘要： A security management method in multimedia middleware of a terminal that can download a multimedia service provided from an external entity. The security management method includes if there is an access request for a particular multimedia service, determining whether there is a corresponding multimedia service; if the access-requested multimedia service does not exist in middleware of the terminal, performing negotiation for secure session setup with the external entity; setting up a secure session to the external entity using a security parameter selected as a result of the negotiation; and receiving information for the download from the external entity through the secure session, and determining whether to execute the download.

    摘要： A texture description method in a frequency domain for extracting texture features by transforming and Gabor-filtering an input image into an image of the frequency domain, and a texture-based retrieval method thereof are provided. The texture description method in the frequency domain includes: a first step of transforming an image of a time domain into an image of the frequency domain; a second step of filtering the transformed image using a Gabor filter having N x M filter regions, where N and M are respective predetermined positive integers; a third step of extracting feature values of the image that has been Gabor-filtered in respective channels of the frequency domain division layout corresponding to the N x M filter regions of the Gabor filter; and a fourth step of deciding a texture descriptor of the image on the basis of the feature values of the image.
