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.

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.

Video stabilization followed by background subtraction using CMOS sensor shows erroneous foregrounds. In this paper, we present a background subtraction method using edge cues and color difference to deal with preprocessed stabilized images. We use a non-parametric background model with edge cues based on the observation that interpolation errors are larger in textured regions than in homogeneous regions. By additional CIELab difference model, we show that misclassifications are dramatically decreased than conventional background subtraction methods.

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.

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, 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.

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.
