In this paper, we present an efficient tile binning algorithm that reduces false overlap area for the Bezier curve. To do so, we propose a Multiple-Bounding Box (MBB) enclosing a Bezier curve with multiple bounding boxes. Experimental comparisons of MBB and legacy methods show that the proposed MBB method reduces 16~35% memory overhead. It also reduces 23~54% CPU latency overhead in a tile-based 2D graphics pipeline.

To provide highly efficient video coding standard, the new high efficiency video coding (HEVC) standard has adopted a recursive quad-tree structured coding unit (CU) and a transform unit (TU). Although the HEVC obtains a very high coding efficiency but it considerably increases the computational complexity because the encoder tests every possible CU in order to estimate the coding performance of each CU. In this paper, we propose a fast CU decision algorithm based on Inter and Intra PU termination for the HEVC to reduce the computational complexity. The proposed algorithm checks code block flag (CBF) value and rate distortion (RD) cost for inter PU prediction. If these two values are satisfied with our present conditions, the next PU process is terminated in the current CU. Experiment result shows that the proposed algorithm reduces the encoding time average 49.56% and 37.3% according to the weighted condition of our proposed algorithm.

In this paper, we propose a real-time multi-person tracking system operating in fixed surveillance camera environment. We adopt particle filtering as our object tracking framework. Background subtraction is used to generate the ROI. And pedestrian detection is used to initialize each tracker. Object size estimation and tracking failure detection is proposed to improve tracking accuracy and robustness. Experimental results demonstrate that the proposed algorithm tracks multiple persons efficiently in real-time.

A home energy management system (HEMS) is expected to play an important role in saving energy costs under time-varying electricity price in a smart home environment. The development of HEMS requires studies on various energy resources in a home, such as energy storage system, and fuel cell. However, in HEMS, very limited research about heating and air conditioning scheduling with customer convenience has been conducted. This study presents a smart heating and air conditioning scheduling method that considers customer convenience and characteristics of the thermal device and an optimization-based approach to minimize the cost in HEMS.

In this paper, we propose an efficient real time tracker that uses a differential evolution strategy within the particle filter framework. Particles are strategically propagated based on the maximum a posterior (most likely) object location with genetic operators. This enables the use of a small sample size and alleviates the frequent sample degeneracy and impoverishment problems encountered in particle filters. We reduce the sample size considerable while improving the trackers accuracy. This makes the proposed tracker a good candidate for real time object tracking or an embedded resource constrained tracker.

In this paper, we propose an unobtrusive a method of daily life monitoring with a triaxial accelerometer embedded in a wrist band. The method recognizes each operation of the activities such as picking up food with chopsticks or eating steamed rice with a spoon and classifies the activities. We believe this method will contribute to the field of innovative health-promoting consumer electronics, which enables consumers to easily and accurately manage their daily life, especially eating activities, and consequently encourage to maintain healthier lifestyle.

High speed transmission for UHDTV cable broadcasting is achieved by adopting MPEG-2 TS basis channel bonding technology. A newly designed TDM frame format based on ITU-T J.183 is proposed. A 181.2 Mbps signal transmitted by a 64 QAM and four 256 QAM channels is received error-free at our prototype set-top box.

This paper presents an interpolation method for ToF depth sensor with pseudo 4-tap pixel architecture. Pseudo 4-tap pixel architecture uses different modulation signals for different row pixels. While faster data acquisition reduces motion artifacts, depth calculation with two vertical pixels lowers depth resolution. The proposed method uses offset values for similarity weights to improve depth resolution. Experimental results show that edge artifact is improved in the vertical direction.
