An image interpolation method is proposed. An input image can be considered to be a deteriorated one from an unknown original image with more pixels than it. The image interpolation can be treated as an underdetermined problem to reconstruct the original image from the input image. In the proposed method, an output image by an arbitrary method is moved closer to the original image by a projection satisfying a reconstruction constraint that the output image should coincide with the input image by an assumed deterioration. Experimental results showed the effectiveness of the proposed method.

Modern flash memory-based storage devices use write buffer not only to reduce the amount of data actually written to the flash memory but also to quickly respond to each write request. A buffered page is flushed to the flash memory as late as possible, expecting possible future write hits, so long as the buffer manager does not select it as a victim for replacement to acquire free space for newly arrived write request. While this delayed-flushing can maximize the buffer hit ratio, in terms of the write response time, it can be a hurdle for fast write response. SSD can respond to a write request only when selected victim pages are safely written to the flash memory and the requested data are written to the write buffer. In this paper, we propose the Proactive Write buffer Flushing (PWF) scheme that proactively flushes a portion of buffered data to the flash memory during the I/O requests intervals. Our simulation study showed that the proposed scheme effectively reduces the write response time with negligible overhead.

Due to the ubiquity of mobile computing, the service provisioning systems are required to provide appropriate services dynamically under the changing context. Based on a model of Kikubari, traditional Japanese manner of hospitality with delicate attention to other's intentions, we propose a context-aware service provisioning system for coordinating multiple users' intentions along with changing context. We evaluate the proposed method with multiple scenarios for the users of a car navigation system and demonstrate the effectiveness of proposed method.

High-speed digital LSIs such as CPU, graphic processing LSI, and System-on-a-chip, are indispensable for all the today's consumer electrics. However, such today's high performance LSIs require careful debugging for timing related errors and high quality delay fault testing for the dependability. This paper presents time-multiplexed on-chip delay measurement to realize fast and high quality timing error debugging and delay fault testing. According to the experimental result, the measurement time of the proposed method is 2.5 % of the conventional one.

3G Internet connections are required for Internet broadcasting with smartphones in outdoor where wireless LAN connections are unavailable. However, it is not easy for the smartphone users broadcast over due to lack of the 3G transmission speed for video streaming in real time. Cell phone carriers, furthermore, tend to shift flat-rate data services to pay-as-you-go data services. 3G data traffic on smartphones should be reduced. In this paper, we propose a still picture Internet broadcasting system with dynamic picture quality adjustment based on audience requests for smartphone broadcasters to achieve stable Internet broadcasting anywhere and optimize amount of data traffic. Since the required bit-rate of still pictures is much smaller than that of the video streaming, still picture Internet broadcasting can reduce data traffic. We introduce a scheme of dynamic picture quality adjustment based on audience requests so that the data traffic can be optimized. This paper reports the design and implementation of the proposed system on a Google's Android terminal. Furthermore, we show the result of an experiment on minimal picture quality.

In this paper, we propose self-synthesis based super-resolution algorithm for natural images. The proposed method analyzes the property of the natural image and focuses on the self-similarity of natural objects. Structure and texture components are extracted from the self-image and synthesized on the interpolated image with matching weights to restore the self-similarity of interpolated image. Then, the synthesized image is compensated with MAP estimator to prevent artifacts. Experimental results show that the proposed method gives more natural texture in terms of human perception.

In this paper, we address an automatic 2D to 3D conversion method intended to generate 3D images which are consistent with both linear perspectives and motion parallax. The method comprises mainly vanishing point tracking and moving object tracking. The experimental result shows generated 3D images have natural 3D appearance.

Fighting game is one of the video games which 2 players fighting in screen by controlling characters. While skilled fighting game players are perceived to have great reflex or judgment like chess players, there is no precise skill evaluation method. In this paper, we suggested surface EMG signal as fighting game skill evaluation method. In the experiment, we divide 10 subjects into skilled group and unskilled group by inputting trial. Furthermore, we measured EMG of their left arms and derived average rectified value. As a result, there were no significant difference of input power, but were input timing between 2 groups.
