The paper presented a technique of generating a CIS video panoramic image without rolling shutter distortion. When an image is captured by a rolling shutter camera in motion during a shuttering time, the captured image showed a distortion due to a rolling shutter mechanism and thus, a panoramic image stitched together with a sequence of those images also looked distorted. To solve the problem, a CIS distortion correction method is applied to a conventional video panoramic image method. The proposed CIS video panoramic image method estimates distortion parameters from two consecutive frames assuming that the global motion of two consecutive frames is affine and then, generates a distortion-free panoramic image while there are artifacts in a conventional video panoramic image.

As several current and emerging Mobile TV systems are made to transparently and efficiently integrate with IP starting from the design phase, Terrestrial Digital Multimedia Broadcast (T-DMB), or DMB also is required to evolve as the IP based service. In the paper, we propose the IP based convergence service for DMB, and the IP based DMB gateway and agents for achieving easy and transparent integration of DMB and IP. And also, we verify the feasibility and benefits of our proposals by implementing some example services.

Management of household appliances and the services have been complicated by increasing of network devices recently. Therefore, Home Gateway (HGW) which manages them intensively has been expected as new consumer electronics. However, HGW has not been popular in our life because the installation cost of HGW is expensive compared with the benefits of services. In this study, we propose new home network system architecture working with not HGW but cloud computing for home management as a resolution. Basic and real-time applications are realized by M2M (Machine-to-Machine) communication between household devices under the local network area and, sophisticated and non-real-time applications are managed on the network cloud and control the household devices via internet. With some examples of home network service, proposed architecture are designed and evaluated at various points of view.

In this paper, a H.264/SVC compliant video client based on a SoC is presented. The SoC includes two processors, a General Purpose Processor to execute a Linux-based operating system and a Digital Signal Processor optimized to decode video sequences. The computational load of the application has been distributed between both processors. The performance results demonstrate that the developed system is able to decode six-layer scalable sequences in real-time.

In this paper, a multimedia data generation algorithm for multi-user video conferencing system over ad-hoc networks is proposed. In the proposed method, the scene-changed frame is estimated using the number of bits pre-encoded by the hardware accelerator and the percentage of the intra-coded macroblocks in each frame. The resulting scene-changed frames are re-encoded as the intra-coded frames and then transmitted to the receiver. Compared to the bit-stream generated from encoding the entire sequence, the proposed algorithm achieves up to about 50% reduction of the bit-rate without skipping the key frames while maintaining the perceptual video quality.

This paper describes a process for analyzing web server requests and responses for use in developing emulation programs for low interaction honeypot responses. In order to manage the complexity of this task, this approach first identifies that static and dynamic resources made available from a web server. Then, for each dynamic resource a fuzzing approach was used to generate and analyze the range of responses for a range of requests, including ones with the types of malformed input that can appear in computer security attacks.

Finite impulse response (FIR) filters are often used for processing audio, communication and other signals. Truncated-matrix multipliers offer reduced area, power and delay at the expense of increased computational error. This paper describes a test bed for low-power FIR-filter hardware accelerators that use truncated-matrix multipliers. It accepts analog input signals, filters them in real-time using an inexpensive field-programmable gate array (FPGA) development board, and produces analog outputs. The input is simultaneously processed using truncated-matrix multipliers and standard multipliers for comparison. Parameters such as filter coefficients, the number of unformed columns and the error correction method can be changed on the fly. The test bed enables real-time testing at the systems-integration level using real analog inputs and outputs.

People in a color image, particularly facial patterns are important and interesting visual object. Thus, color reproduction for skin tone becomes the foremost treatment, because skin color is a key memory color in color application systems. Previous studies suggested skin color reproduction by mapping only to the center value of preferred skin region. However, it is not suitable to determine one preference color because preference color from the observer's preference test is not dominant. In this paper, selective skin color reproduction using preferred skin colors is proposed. The proposed method first defines preferred skin colors according to their luminance level. Next skin color is detected by using skin and feature map. After that, each corresponding preferred skin color is determined for each skin region. Finally, input skin color is proportionally mapped toward preferred skin color according to the difference between input skin color and preferred skin color, smoothly reproducing skin color. Through the experimental results, the proposed method achieves preferred skin color reproduction.

In order to facilitate the interference manipulation, the ATSC recommended practice (RP) A/110B introduces transmitter identification (TxID) signals with very low level, which are embedded in the DTV signal to be transmitted from each transmitter and repeater. Also, the TxID signals can be used for a very low-rate additional data transmission in ATSC DTV systems. In this paper, we propose an improved robust data transmission system based on Walsh sequences and RS (Reed-Solomon) code for the ATSC terrestrial DTV systems. The proposed system significantly improves the robustness compared to the conventional system.
