Cognitive radio is an effective technology to improve spectrum utilization through spectrum sharing among primary users (PUs) and secondary users (SUs). Developing accurate and efficient methods to determine the PU coverage is crucial in order to avoid potential interference from SU to PU. In this paper, we propose to use the estimated location of each SU, which is obtained using the self-organ...

Genome-wide association studies (GWAS) have identified many genetic factors underlying complex human traits. However, these factors have explained only a small fraction of these traits’ genetic heritability. It is argued that many more genetic factors remain undiscovered. These genetic factors likely are weakly associated at the population level and sparsely distributed across the genome. In th...

In today’s technological world images plays a very important role. Images are very helpful in several fields like non-destructive testing. Medical diagnostics, surveillance and military etc. in image analysis and computer vision edge detection and boundary detection plays a very fundamental role. For image interpretation tasks and in image analysis processes the boundary of image will provide v...

This paper proposes a real-time distributed algorithm for a team of smart cameras to self-organize and perform video surveillance of an open boundary. In particular, our algorithm simultaneously partitions the boundary among the cameras, and synchronizes the motion of the cameras to optimize the surveillance performance. We focus on the detection of smart intruders, who are aware of the cameras...

Video Shot-Boundary Detection is important for video analysis, segmentation and retrieval. The detection results of Shot-Boundary are not only relation with two nearest frames of shot cuts, but also their several neighboring frames. Video stream is multistream time sequence. Grey model based on set sequence (SGM) is proposed to analyze and process multi-stream time sequences constructed with sa...

Digital video is widely used in multimedia databases and requires effective retrieval techniques. Shot boundary detection is a common first step in analysing video content. The effective detection of gradual transitions is an especially difficult task. Building upon our past research work, we have designed a novel decision stage for detection of gradual transitions. Its strength lies particular...

Experiments on accent type recognition and syntactic boundary detection of Japanese speech were conducted based on the statistical modeling of voice fundamental frequency contours formerly proposed by the authors. In the proposed modeling, fundamental frequency contours are segmented into moraic units to generate moraic contours, which are further represented by discrete codes. After modeling t...

We have been developing a reliable method of prosodic word boundary detection for Japanese continuous speech based on the statistical modeling of mora transitions of fundamental frequency contours of prosodic words. Modifications in the codebook sizes and in the HMM topologies improved the boundary detection performance. When using mora boundary information obtainable from the phoneme recogniti...

Boundary detection is essential for a variety of computer vision tasks such as segmentation and recognition. We propose a unified formulation for boundary detection, with closed-form solution, which is applicable to the localization of different types of boundaries, such as intensity edges and occlusion boundaries from video and RGB-D cameras. Our algorithm simultaneously combines lowand mid-le...
