In the ICCE2011 which is one of the largest technical conferences related to consumer electronics, keynote speeches and technical sessions are programmed according to the main conference theme of this year: The future of digital media. In the technical sessions, various research fields of papers are presented, which range from basic techniques and their applications of traditional CE products like DTV, recorder, and digital camera, to a new trendy technologies such as 3D and smart grid. The number of oral and poster presentations is substantially increased because the actual conference days are extended to four days from the previous three-day conference. As a new trial, free mini tutorial sessions and Nokia-sponsored demos are performed, which are well attracted by the attendees.

Among a lot of proposals for super resolution image reconstruction, learning-based method seems to be successful approach. But, the learning-based method still has several problems. In this paper we propose a new learning-based approach for super resolution image reconstruction utilizing Total Variation (TV) regularization method.

In this paper, we propose a distinction method of road surface conditions by using only video information from a visible video camera. The feature of this method is simply to use the cars' headlights as the light source. In this method, using the probability function of brightness, we extract the road area that is having moderate quantities of light, touched by the headlights. Then, we differentiate two road surface conditions such as dry and wet, by using texture features. As a result, by using this method, it became possible to distinguish the road surface conditions with high accuracy.

We have so far proposed a new distributed mobile storage architecture to store data in a designated local area. This is achieved by collaborated end-terminals without an infrastructure network. In this paper, new relay data algorithms are proposed to bring a lower overhead communication and a more robust storage capability. Simulation experiments show the effectiveness of the proposed control algorithm from the communication cost and the length of storage time.

We present the design of an apparatus that creates a personal private communication channel over computer-embedded devices. The apparatus distributes security via location-limited channel to devices and helps the devices negotiate encryption keys. The prototype implementation of the apparatus demonstrated that it can securely and intuitively link devices with no contact with an online server while imposing low overhead.

We propose a marker-less Augmented Reality (AR) application on user's hand based on a fast fingertip detection technique for smart phones. A conventional hand-based marker-less AR system does not have enough accuracy and speed in human hand detection on a mobile device. This paper presents a fast hand position and posture estimation algorithm based on a fast and robust detection of non-skin regions around the hand. The proposed method realized rendering of virtual 3D models on a hand over 10 frames per second (fps) on a smart phone. Simulation results show that we can archive up to 90% complexity reduction and more accurate than the conventional method.

This paper proposes an algorithm to estimate the useful content for known groups. The method makes it possible to recommend for the group such as friends, couple and family. As the first step, we focused on the preference between group members. Our algorithm estimates the preference using rating of individual for video genres and viewing history shared together. Then we judge that the content is useful for the group based on the preference. Evaluation tests show that our proposal algorithm is serendipitous.

Extended variable-length mode coding (EVLC), which dynamically creates code words for coding modes by taking account of the spatio-temporal correlations, is proposed. Experimental results show that EVLC achieves average bit-rate reduction of 2.29% and a maximum bit-rate reduction of 6.84% compared to H.264/AVC with negligible increase in computational time.
