A real-time handheld indoor positioning device is developed, featuring 2 novel perfectly complementary positioning methods: 1) RFID Heron-bilateration location estimation, based on external RFID infrastructure, and 2) IMU angular-driven navigation reckoning, based on internal IMU module. At first, 2 or multiples of 2 active RFID tags as infrastructure landmarks are deployed along the surrounding walls in a single indoor space or room. After the infrastructure landmarks are set up, the handheld indoor positioning device begins to connect to the Bluetooth-based RFID reader by pairing with Bluetooth ID of the RFID reader. Then, on the screen of the handheld indoor positioning device, red landmarks on the 2D indoor map represents pre-deployed active RFID tags. When moving, the targeted handheld indoor positioning device keeps estimating the relative location through external RFID infrastructure and keeps reckoning the inertial navigation through internal IMU module. Furthermore, this work proposes and develops Kalman-filter drift removal, linear-like RSSI-to-distance transformation, RFID Heron-bilateration location estimation, and IMU angular-driven navigation reckoning, to improve the accuracy and reliability of positioning. Finally, the screen of the handheld indoor positioning device can show the location and orientation indications of the targeted user on the 2D indoor map accurately and immediately.

Steganography is the science of secret data communication using carrier medium, such as images, videos, text, and networks. Image steganography is majorly divided into spatial and frequency domains. Pixel value differencing (PVD) considered as good steganographic algorithm due to its high payload and good visual perception in spatial domain. The purpose of this paper is two folded. First is the critical analysis of current PVD methods using evaluating parameters (payload, visual quality and resistance of attacks) and secondly it highlights the current promising directions on PVD steganographic research.

Live streaming services have been developed prosperously in recent years. With live streaming services, broadcasters broadcast their videos to attract large numbers of viewers to watch. Some live streaming services also provide a platform for viewers gathering together to watch channels and interact with others. Over hundreds of videos broadcast every day, recommending channels are necessary to help viewers finding channels of interests. In this paper, we propose the hybrid HITS algorithm for Channel Recommendation (HyHITS_CR) which adopts the HITS algorithm with modification to utilize the follower-followee relationship on channel recommendation. Besides, we also observe from real logs that some viewers may focus on few particular channels. Thus, HyHITS_CR also takes advantage on such observation to further improve the accuracy of recommendation. Experimental results show that the hit rate of HyHITS_CR is around 10% higher than other prior algorithms.

In this paper, we present a portable SOS device with wireless communication. This device is based on all-digital-phase-locked-loop (ADPLL). A wake-up mode is implemented for low power consumption. With extra biological sensors attached to the users, the device is awakened by abnormal signals and actively sends a SOS signal for help. Moreover, it can use those sensors to collect information from users. This information can be modulated to RF frequency and sent out along with the SOS signal. The SOS device also can be used in passive mode with a SOS button in some emergency situations.

We also show the tags which affect social popularity in each service and discuss the characteristics of popular contents in each service by analyzing these results.

The current study describes a technique for reconstructing a three dimensional surface from multiple images of the (single camera) endoscopic video. A 3D shape of the scene in each image frame of the endoscopic video was reconstructed using shape from shading technique. The characteristic feature points on the 2D images were detected using SURF algorithm and the features were matched using BRIEF and Hamming distance criteria. The matched feature points between the consecutive frames were used to find the transformation matrix to align the 3D surfaces of the consecutive video frames. Using the transformation matrix, the 3D surfaces were stitched (registered) together. The method was applied on a recorded video of the laparoscopic surgery. The reconstructed surface provides a wider view and depth information to the viewers.

Currently, most of the human detection methods are based on low-level features. In this paper, we proposed a middle-level feature generation method based on non-negative matrix factorization (NMF) for human detection. We also proposed an improvement scheme to guarantee that a better middle-level feature can be achieved. The proposed scheme can be applied to a complex background and the experimental results are better than those when only the low-level feature is involved.
