Due to the fact that different queries to a content-based image retrieval (CBIR) system emphasize different subsets of a large collection of features, most CBIR systems using only a few features are therefore only suitable for retrieving certain types of images. In this research we combine a wide range of features, including edge information, texture energy, and the HSV color distributions, forming a feature space of up to 1053 dimensions, in which the system can search for features most desired by the user. Through a training process using the AdaBoost algorithm 9 our system can efficiently search for important features in a large set of features, as indicated by the user, and effectively retrieve the images according to these features. The characteristics of the system meet the requirements of mobile devices for performing image retrieval. The experimental results show that the performance of the proposed system is sufficiently applicable for mobile devices to retrieve images from a huge database.

The application, Zurfer, supports viewing of photos from the user, their contacts, and the general user population. Photos are organized using a channel metaphor, driven by multiple dimensions: social, spatial and topical. Zurfer was deployed to over 500 users; extensive user research was conducted with nine participants. The data from the deployment and the study exposes general themes of mobile application use, as well as requirements for mobile applications in the photos domain, mobile social applications, and entertainmentdriven mobile applications.

The use of SIP in All-IP mobile phones is a step toward achieving supernetworking, providing the user with powerful yet conceptually simple tools for sending and receiving multimedia content over a wireless network. The analysis includes an introduction of the application supernetworking concept in detail, with insight into the role of SIP in the current and future implementations.
