Quality of image super-resolution (SR) degrades by noise component. However it should not be eliminated because it is important for high definition impression for digital cinema. Therefore we propose an image SR method by synthesis of resolution-enhanced signal and noise components respectively after dividing an original image into signal and noise components. The signal component is resolution-enhanced using image registration between the signal component and its wavelet multi-scale components with resolution-enhanced parameter optimization.

High Efficiency Video Coding (HEVC) is the next coding standard that is being finalized by ITU's Joint Collaborative Team on Video Coding (JCT-VC). This paper compares the H.264/AVC, current coding standard, and HEVC (aka H.265) in mobile compute environments. In this study, the focus, within the mobile compute environment, are smart phones. The major smart phone elements are smaller screen size, which is typically 3.5 inches diagonal to 5.0 inches diagonal for high end smart phones and typical cellular network bandwidth, which is typically 3G or faster. There is compelling subjective test feedback that indicates human device interaction focused on user's experience is very similar between HEVC and H.264 encoding standards for mobile environment screen size and higher cellphone bandwidth (such as 400kbps constant bit rate). This suggests the benefits of HEVC over H.264 in mobile environment are not as clear.

A low-complexity depth generation algorithm for 3D conversion of 2D videos is presented. For temporal consistency in global depth, a pattern-based depth generation method is introduced. In addition, refinement of depth from the combined depth cues of texture and motion is also addressed. Experimental results show that the proposed method outperforms previous algorithms in terms of the complexity and subjective quality.

To match two images with a large scale difference, a scale parameter can be introduced into the warp parameters of the KLT tracker. For some images, the KLT tracker with the scale warp parameter fails to converge. We assume that this result is caused by the singularity of the Hessian matrix. An improved KLT tracker is proposed to avoid this tracking failure. The proposed method introduces an index (scale invariance index) to determine how close the Hessian matrix is to a singular one with the scale warp parameter. According to the index, either of two different sets of warp parameters is selected: one is with the scale warp parameter and the other is without it.

This paper presents a novel stereoscopic image processing pipeline which ensures the consistency of a stereoscopic image pair. Although a stereoscopic image calibration method should resolve both photometric and geometric binocular asymmetries, most previous approaches [1], [2] have mainly focused on the geometric calibration so far. In contrast to this biased research, we propose both photometric and geometric calibration methods which are readily applicable to an embedded pipeline for a stereoscopic camera system. The experimental results demonstrate the performance of the proposed pipeline for calibrating a stereoscopic image pair.

A memory reduction method of luminance compensation algorithm using luminance sensor is proposed for high resolution mobile active matrix organic light emitting diode (AMOLED) display applications. The proposed method can be applied to AMOLED panels which have poor luminance uniformity even though compensation pixel circuit is used. Measurement results show that the deviation of luminance error is reduced from 18.1% to 3.8% when the proposed algorithm is applied to 5.3-inch AMOLED panel using threshold voltage compensation pixel structure.

Recently, a healthcare system utilizing electronic technology is attracting attention in the world. People are becoming increasingly conscious about health. Current healthcare services increase health awareness by providing information, but don't utilize the information. Moreover, medical service has problem of lacking the concept of prevention. For those problems, this research proposes a lifestyle improvement support system which shows user how to use advice. At the time of shopping and cooking, the system provides advice that match user's context. By using the context, the system provides proper advice. The previous research found that user's lifestyle is deeply related to the content of advice. In order to solve those problems, this research includes budget, work load, time in advice as context. This research performs a comparative evaluation of the proposed algorithm and the algorithm of the previous paper.

We proposed the light field acquisition system using the wedge-shaped waveguide. To obtain the light field reflected from the object, the lens array is mounted on the wedge-shaped waveguide. The light field information is forwarded through the waveguide and captured. In the experiment, we obtained the light field image variant with the object distance.

Existing visual representation and control restricts the access of visually impaired people to information in touch screen devices, but a flexible touch interface and multimodal representation can provide easy accessibility to blind users. To improve the accessibility of touch screen devices for visually impaired people, we propose a new approach to information representation and interaction using the concepts of `background display' and `foreground display'. Background display is defined as indirect representation elements, such as color, size, and location. Foreground display is defined as direct representation elements, such as text. We use auditory and tactile modality to present background display, and auditory display is used for foreground display. We found that blindfolded users understood the information on buttons more effectively and performed touch input tasks more quickly when background display was offered.
