The use of MMW images has been proposed recently in the biometric field aiming to overcome certain limitations when using images acquired at visible frequencies. In this paper, several body shape-based techniques are applied to model the silhouette of images of people acquired at 94 GHz. Three main approaches are presented: a baseline system based on the Euclidean distance, a dynamic programming method...
Present trend towards multiprocessor and multi-core architectures as well as programmable NICs (Network Interface Cards) provides new opportunities to exploit the available parallelism in the network interface design and implementation to cope with the high communication overhead required to take advantage of a multi-gigabit links. In this paper we have used dynamic web servers to evaluate several...
Touch screen-enabled devices are proliferating in the communications and entertainment markets. In this scenario, the use of graphical passwords for user validation is receiving an increasing interest in the last years. Unlike in other fields of research on automatic user authentication, such as biometrics, there are no public databases of graphical passwords usable for research purposes (to the extent...
The availability of multi-core processors and programmable NICs (Network Interface Cards), such as TOEs (TCP/IP Offloading Engines), provides new opportunities for designing efficient network interfaces to cope with the gap between the improvement rates of link bandwidths and microprocessor performance. This gap poses important challenges related with the high computational requirements associated...
