In a typical recognition system, the inclusion of more training data is likely to increase the recognition rate. However, it is not easy to obtain large training sets. Focusing on practical applicability such as controlling home appliances, we propose a hand gesture recognition method from one example that is computationally efficient and can be easily implemented. 3D hand motion trajectory is achieved from a depth camera and then normalized for translation invariant feature extraction. Based on the simple K-NN classifier, we develop a pattern matching method by combining the DTW (Dynamic Time Warping) algorithm and a statistical measure for similarity between two random vectors. We conducted computational experiments on hand gesture data and compared the results with those derived via conventional DTW recognition.
在一个典型的识别系统中，包含更多的训练数据可能会提高识别率。然而，获得大的训练集并不容易。着眼于实际应用，例如控制家用电器，我们从一个例子中提出了一种计算效率高且易于实现的手势识别方法。从深度相机获取三维手部运动轨迹，然后归一化进行平移不变特征提取。在简单的K-NN分类器的基础上，我们开发了一种结合DTW (Dynamic Time Warping)算法和两个随机向量之间相似度的统计度量的模式匹配方法。我们对手势数据进行了计算实验，并将结果与传统的DTW识别结果进行了比较。

This paper proposes a topic linking using a robust video signature to detect visual duplicates for grouping coherent topics in a video archive. The proposed video signature, which was accepted as part of a new ISO/IEC standard “MPEG-7 Video Signature Tools”, is designed for robust and high-speed detection of visual duplicates in a large database. It represents intensity differences between various sub-regions in a frame, which provides robustness to various modifications to videos, including caption overlay and compression. We show that the proposed video signature significantly improves the detection rate of visual duplicate segments, by more than 40% under caption overlay, compared with conventional visual features. We also present our topic linking system with its visual presentation of topic groups for efficient browsing and viewing of videos.

Advanced interference management schemes have become crucial for achieving the required cell edge spectral efficiency targets and to provide ubiquity of user experience throughout the network, actively discussed for 4G and beyond 4G cellular standards. On the other hands, it requires the significant channel state information (CSI) feedback overhead on consumer units so as to promote the cell-edge performance. In this paper, we explore the interplay between interference management, device-to-device (D2D) communication, and CSI feedback. To show this, a novel interference management method, D2D communication assisted interference alignment (DIA) is proposed, which is inspired by subspace intersection property. We believe that the proposed technology can be well applied to consumer mobile communication devices over cellular networks such as smart phones, tablets, etc.

The conventional approach cannot meet the requirement of physiological signal analysis to extract the main component of the acquired signal. This paper proposes a non-uniform sampling strategy with corresponding fast Fourier transform (FFT) for signal component analysis. The simulation results of different approaches are analyzed and compared. The proposed strategy has the superior anti-aliasing performance than conventional approach with lower sampling rate.

A new coefficient scanning method using context adaptive block scan (CABS) is presented. A number of additional scan patterns for entropy coding are employed in addition to the conventional zigzag scan. The scan pattern is adaptively selected per 4×4 block basis. In order to avoid any increment of overhead bits, the scan pattern for each block is determined in the context adaptive manner.

This paper proposes a fast Operating System (OS) Switcher for ARM-based Consumer Electronics (CE) such as Smart Phones, Tablets and IPTVs. The OS switcher enables users to utilize multiple OSes on single H/W device without security problem from interference among OSes. The OS switcher is notably faster than the multi-boot approach and can preserve the previous working states. The OS switcher does not burden any run time overhead compared to virtualization and can be easily applied to the new product. We implemented the OS switcher in the bootloader layer without any modification of OS.

Graspable user interface (UI) is a useful method for interacting with virtual world. It allows users to hold and manipulate a device intuitively for manipulating virtual 3D objects. In this paper, we propose Grip-Ball as graspable UI, which is a spherical shaped device based upon capacitive multi-touch sensing. User's grip pattern can be recognized by measuring grip touch on the surface of the device. In the study, we define 5 hand-grip patterns of the Grip-Ball according to user's purpose (platform, power-grip and precise-grip) and number of hand (one-handed grip, two-handed grip). An accuracy of up to 98% could be achieved for hand grip recognition.

We propose a meanshift segmentation based inverse colorization method for image compression. The encoder makes use of the meanshift segmentation algorithm in automatically selecting the representative pixels from the original image from which the colored image is reconstructed by the decoder. Using the modes of the clustered regions as the representative pixels, the compression rate becomes high and the reconstructed image has good visual quality.

We implement the Aggressive PNN method on GPUs by using CUDA to generate codebooks for VQ compression and the speedup of up to 4.01 is achieved compared with the tau PNN method on the CPU. Our second method enhances the parallelism by using indirect vectors to reduce idle threads. We also improved the algorithm by about 20% by using indirect vectors.
