High-quality image enlargement is achieved by the augmentation of the high-frequency components that deteriorate as a result of image enlargement. A codebook-based method, which utilizes the relationship of the low- and high-frequency image components, is a proven method of high-quality image enlargement. However, this method requires a significant calculation time to be employed for a codebook search process, and thus is not suitable for real-time processing. In this paper, we propose a fast image-enlargement algorithm that includes a hierarchical predefined codebook and a fast edge-patch detection rule. A hierarchical codebook search reduces the number of comparisons that need to be made in comparison with a conventional full codebook search. In addition, applying the augmentation of the high-frequency components to only the edge patches detected under the proposed rule reduces the calculation time. The experimental results show that the calculation time of the proposed method is around 180 times faster than that of the fastest existing codebook-based method. The proposed method realizes high-quality image enlargement in terms of both objective and subjective evaluations in comparison with conventional methods. © 2013 ICIC International.

Live demonstration: Internet Booster a novel WEB application platform accelerated by reconfigurable virtual hardware circuits 査読有り

This live demonstration presents an Internet Booster (IB) which is a novel WEB application platform accelerated by virtual hardware circuits. Akey-idea of IB is obtaining relevant WEB applications virtual hardware circuit through the Internet. The downloaded virtual hardware circuit is dynamically reconfigured into an FPGA and cooperates with software and network to accelerate WEB application. In order to realize the concept of IB, we develop a hwModule VC FPGA Cardbus board and a networked hw/sw complex system to access virtual hardware circiuts via the Internet. Furthermore, we also develop a virtual hardware video codec and a TCP/IP hardware stack to construct a demonstration system. In the live demonstration, we show a WEB streaming application accelerated by IB on the local area network environment. The demonstration system achieves full-color VGA size (24 bits RGB, 640 × 480 pixels) video streaming with around 20 frames per second. © 2012 IEEE.
