The semi-supervised kernel logistic regression (SSKLR), developed for the classification of human behaviors from sensor data, takes the form of a linear combination of kernel functions associated with each of the labeled and unlabeled data from the training set. Its model parameters are determined, using an EM algorithm, by maximizing the expectation of the joint distribution over the posterior for selected unlabeled data that are in a neighborhood of one of labeled data. Tests for two types of human behaviors such as (1) "walk," and "skip," and (2) "drink a cup of tea," and "wash a cup" reveal that, using acceleration data as input, SSKLR classifies the behaviors better than semi-supervised Gaussian mixture and semi-supervised support vector machine models.

This paper presents the coding efficiency impacts using larger intra prediction unit size (PU extension) than HEVC, which is implemented on the HEVC reference software HM-16.4. It is reported that the PU extension up to 128×128 can achieve 0.07 % and 0.19 % on average for normal QPs (QP=22, 27, 32, 37) and high QPs (QP=32, 37, 42, 47) respectively in all intra configuration. The amount of gain by 128×128 Intra PU extension is roughly as half as that of 64×64 Intra PU of 0.18 % and 0.45 % for normal QPs and High QPs. For further study, the number of prediction mode increase, efficient prediction mode signalling and transform size extension should be studied.
本文通过在HEVC参考软件HM-16.4上实现比HEVC更大的帧内预测单元(PU扩展)对编码效率的影响。据报道，在所有intra配置中，正常QPs (QP=22、27、32、37)和高QPs (QP=32、37、42、47)的PU延伸率平均分别达到0.07%和0.19%，最高可达128×128。对于正常qp和高qp, 128×128 Intra PU扩展的增益量大约是64×64 Intra PU的一半，分别为0.18%和0.45%。为了进一步研究，需要研究增加预测模式的数量、有效的预测模式信令和变换大小的扩展。

In this paper we propose a novel method to measure the contrast reduction in a digital image, and its application on LCD backlight dimming. The contribution of this paper is twofold. First, we propose a new key concept, burstiness, in measuring the contrast reduction. Second, there has not been a backlight control method that quantifies the image quality degradation in terms of contrast reduction, and optimizes it with power consumption. By considering the spatial distribution characteristic of contrast reduced pixels, the proposed method effectively captures the contrast reduction. This leads to a gain in the power saving in the backlight dimming while visual perception quality is maintained.

In this paper, we propose a low complexity depth video compression approach for the Microsoft Kinect device. In this framework, the depth image is transformed through divisive normalized bilateral filter (DNBL) and through padding in order to remove failure in the depth map. Furthermore, in order to reduce the computational complexity, in the filtering process, we employ blocks partition, where each non-overlapped block uses a different window size based on the detected edge information. The reformed depth map is then fed into the H.264/AVC encoder. The experimental results show that the proposed approach can reduce the computational complexity while maintaining the performance.

In this study, we developed an audio system that is made up of speaker system of regular polyhedron enclosure, and multi channel digital audio amplifier. The speaker system has loudspeaker units that are independently wired out of the enclosure, and are controlled independently. The amplifier can control their output timing and amplitudes independently and precisely. With this combination, we aimed to spuriously deform shape of the enclosure. In this demonstration, we show a trial implementation, and hope you to sense the effect, and wish to hear your impressions and advises.

In recent years, Bluetooth beacon gets much attention on location-aware services. To obtain an accurate position in a room, we use signal strength of Bluetooth beacons and develop position estimation methods. In our college, we aim to introduce the position estimation system on college. We have installed a number of Bluetooth beacon devices in and around a room and observed RSSI of beacons by portable devices to achieve fundamental knowledge of beacons and estimate their position. In this paper, we take some experiments on different phenomena and with different devices. We confirm that our method can separate completely whether a device is in a room or not. Results show that the average error between device position and estimated position is 2.4m.

This paper proposes "Haconiwa," a toolkit for learning how to build a basic electronic circuit intuitively. The toolkit is intended to motivate participants to develop an interest in electronic circuits. The toolkit aims at fostering the interest of participants in electronic devices and provides users with the pleasure involved in making products. The toolkit consists of two types of modules: basement modules and object modules (e.g., LED, battery, and switch). Users can customize the appearance of the object modules by decorating them with fancywork. By connecting the decorated modules with the basement modules, users can make their own original miniature scenery.

Miniaturization of computation, thanks to Moore's Law, goes to every object including those that we wear and stand around us. This trend is facilitated by the introduction of general purpose modules that extend the community of designers to include unskilled creatives. Printed Electronics, using organic materials instead of silicon, makes it possible to create edible, disposable and perishable IoT devices. 3D Printing can embed electronic materials into any bearing structure, transforming dumb objects into digitally alive ones through Structural Electronics. The spread of smart devices fosters the development of super batteries, energy harvesting and wireless transfer. In this work these trends towards a disappearing electronics are described and analyzed.

Digital home is a popular technology. Various applications are provided, such as home surveillance and power saving. Users can subscribe desired applications and execute them on mobile gateways or home gateways. However, there are no exiting technologies that can automatically activate/migrate/discover applications among gateways. This paper proposes an application management scheme, which manages the application by considering their utility and cost basing on the information in their provided profiles. Applications can be activated/deactivated and transferred under different conditions, and the management and execution cost can be reduced. The results of the elaboration show that the proposed scheme can effectively reduce the manual control overhead and the energy consumption.
