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.

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.

Video stabilization followed by background subtraction using CMOS sensor shows erroneous foregrounds. In this paper, we present a background subtraction method using edge cues and color difference to deal with preprocessed stabilized images. We use a non-parametric background model with edge cues based on the observation that interpolation errors are larger in textured regions than in homogeneous regions. By additional CIELab difference model, we show that misclassifications are dramatically decreased than conventional background subtraction methods.

We propose an efficient single reference superresolution system based on the discrete wavelet transform. We assume that the low-resolution image to be enhanced is the low-frequency subband of the high-resolution image to be reconstructed. We design a support vector machine synthesizing the high-frequency subband based on the inter-subband correlation of the directional edges. Experimental results of sample images show that the proposed system offers improvements in terms of both measured distortion and subjective appearance.

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.

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.

This paper discusses a cooperative reception technique for Japanese digital terrestrial television broadcasting "One-segment service" using multiple terminals. In this paper, received signals and the channel information are transmitted by using one-way or two-way communication. Maximum ratio combining scheme are performed in the own terminal using the exchanged channel information. The error rate performance can be improved by using multiple receiving terminals in the One-Segment Service.

We propose pointing gesture-based large display interaction using a depth camera. A user interacts with applications for large display by using pointing gestures with the barehand. The calibration between large display and depth camera can be automatically performed by using RGB-D camera. The experimental result shows that the pointing accuracy is 96.2%. We demonstrate the puzzle game application using the proposed system.

This paper presents a new intra prediction technique for HEVC, which is next-generation video coding standard that has collaboratively been developed by ISO/MPEG and ITU-T/VCEG. On intra coding for HEVC, extension of MPEG4-AVC/H.264-like intra prediction scheme has been studied. In this conventional scheme, the prediction block is generated by simply copying adjacent reference samples, interpolating the reference samples toward prediction direction or averaging the reference samples. Thus, signal discontinuity between prediction block and adjacent reconstructed blocks could occur, which causes loss of coding efficiency of residual signal. In this paper, we propose an adaptive filtering scheme for intra prediction samples generated by either DC or directional prediction that solves the above issue. According to our evaluation, the proposed scheme achieves approximately 0.6% bitrate savings on average compared to the conventional AVC-style intra coding.
