Sleep mode detection is one of the significant features of power management and green computing. However, for a television or a smart TV, it is difficult to detect a deactivation event because the user can use these devices without input from an input device. We propose a robust method to detect deactivation events based on a vision approach involving face detection and motion detection for a smart TV. Experiments are performed on a large dataset. The proposed approach significantly reduces false detections of faces and complement missed humans by means of motion detection.

In this paper, we propose a new rate-2, 2×2 spacetime block-code (STBC) with low complexity maximum likelihood (ML) detection. We focus on the operation under low signal-to-noise ratio (SNR) regions. Numerical results show that the proposed STBC outperforms the conventional rate-2, 2×2 STBC of WiMAX under low SNR regions. Also, the ML detection complexity of the proposed STBC is significantly reduced.

Remote monitoring of heart disease patients has been shown to be effective for diagnosis and detection of arrhythmias. We propose a remote cardiac monitoring system for preventive care by developing a decision support system with personalized parameters and an algorithm to predict forthcoming paroxysmal atrial fibrillations. The system consists of several physiological measuring devices, mobile gateways, point-of-care devices, and a monitoring server. The proposed prediction algorithm shows 87.5% accuracy.

Performance of a speech recognition system often degrades severely under low SNR environment. To overcome this difficulty, the visual signal is also considered as an additional aid these days. In this paper, we address speaker dependent visual speech recognition problem using Extended Curvature Gabor (ECG) wavelet. First, lip image sequences are filtered using the ECG, because the variation of the filter response well represents the lip movement. Next, the distance between the output and training data is calculated using the Multi Dimensional Dynamic Time Warping (MDDTW) with new cost matrix. Finally, the lip sequences are classified into the corresponding utterance. In this process, the parameters of ECG must be selected appropriately, where we compare a simple greedy selection method and selection scheme based on AdaBoost.

In this paper, we propose a fast adaptive power allocation algorithm for an orthogonal frequency division multiple access (OFDMA) system that employs an adaptive modulation and coding (AMC) scheme to significantly reduce the processing time. We show that the proposed algorithm reduces the complexity by M -the number of AMC levels- times compared with greedy adaptive power allocation (APA) which is known as the optimal algorithm for power allocation problem while still maintaining the utility at the same level as greedy APA.

We present a new audio steganographic technique based on empirical mode decomposition and Hilbert Transform. The audio signal is decomposed into several intrinsic mode functions to be the addressee for the payload of a QR code. Our results show that the proposed method is robust against common audio processing attacks.

A parallel pipelined array of cells suitable for realtime computation of histograms is proposed. The cell architecture builds on previous work to now allow operating on a stream of data at 1 pixel per clock cycle. This new cell is more suitable for interfacing to camera sensors or to microprocessors of 8-bit data buses which are common in consumer digital cameras. Arrays using the new proposed cells are obtained via C-slow retiming techniques and can be clocked at a 65% faster frequency than previous arrays. This achieves over 80% of the performance of two-pixel per clock cycle parallel pipelined arrays.

Relay users play a significant role in cooperative communication system improving the overall performance by increasing reliability. First, based on code division multiple access (CDMA) techniques, we propose a network coding (NC) based CDMA cooperation, which consumes less time slots in either synchronous or asynchronous transmission. Further, NC-based cooperative system saves transmission bandwidth, in other words, we show that it reduces outage probability as compared to the traditional cooperative communication system. These results are shown considering a Nakagami-m fading channel.

In this paper, an automatic method for extracting visual saliency based on selective integration of feature maps in frequency domain is proposed. Feature maps are calculated by measuring the Bayes spectral entropy. In order to extract visual saliency effectively, feature maps are first generated from three images separated into Y, Cb, Cr channels, respectively. Then, by selectively integrating feature maps, visual saliency is finally extracted. Experimental results have shown that the proposed method obtains good performance of visual saliency under various environments containing multiple objects and cluttered backgrounds in natural images.
