An image copy detection scheme is proposed by using Harris interest points.

As the important base of the urban management information system, the point of interest plays a big role, which the accurate and quick positioning of the urban component and event depends on.

To solve the problems that the POI datas lacked of unified specification and effective means of broadcast timely in location-based mobile services,this paper introduced a novel method to embed the point of interest messages into transport protocol experts group and described the implementation of TPEG message broadcasted over MBMS using the stream delivery method.

Image mosaic method based on orientation feature of interest point;

Most existing methods for determining location of interest point in image detection are,in our opinion,still deficient in precision.

The method defines all the pages in the same content of page hierarchy as an interest point,and extracts interest points in a session.

A novel image retrieval algorithm based on the color anddistribution of interest points;
