    Future ubiquitous computing environments integrate the services of everyday objects equipped with tiny processors and sensors into distributed applications. These smart devices can communicate with each other and also explore their environment. In order for the applications to function properly, policies need to be defined, which determine ways that they can be used, protected, changed, etc. A pol... View full abstract»

    Personal memories as expressed through narrations, photos or drawings, published or confined texts, often describe events that have occurred in cities, in time these personal memories are melded into a collective memory attached to the physical space. Collective memory is closely related to location, refers to a time period and reflects the social interactions of people who share it. All these par... View full abstract»

    Publication Year: 2011, Page(s):12 - 17
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (335 KB) | HTML iconHTML

    With the help of recent development on semiconductor design and process technologies modern processors can provide a great opportunity to increase the performance of processing multimedia data by exploiting task- and data-parallelism in heterogeneous system consisting of multi-core CPUs and many-core GPUs (graphical processing units). This paper presents an optimization of 2D DCT (discrete cosine ... View full abstract»

    This paper proposes a novel object-based virtual network middleware for supporting the interoperability among home devices and smart grid devices. In order to demonstrate that home devices and smart grid devices are interoperable through the proposed middleware, we implement applications based on the OVNet on a target platform consisting of embedded boards, sensors and laptops for emulation purpos...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (498 KB) | HTML iconHTML

    The design of message routing algorithms and its performance evaluation in disconnected mobile P2P networks are challenging issues due to its high dynamic evolving topology. To capture the evolution of the connectivity properties of such networks, a Time-Evolving Graph (TEG) model is proposed in this paper. Our intuitive observation is that the connectivity graph of a dynamic network can be obtain... View full abstract»

    In large-scale wireless sensor networks, multicast is an important routing service for the efficient data distribution required for activities, such as filtering scheme updates, the redistribution of the cryptography keys and targeted queries. Especially, the redistribution of cryptography keys is important for the robust secure communication within the multicast group. In this paper, we propose a... View full abstract»

  • A High-Capacity CDMA Watermarking Scheme Based on Orthogonal Pseudorandom Sequence Subspace Projection

    Publication Year: 2011, Page(s):33 - 38
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (304 KB) | HTML iconHTML

    In this paper, we propose a high-capacity CDMA based watermarking scheme based on orthogonal pseudorandom sequence subspace projection. We introduced a novel idea to eliminate the interference due to the correlation between the host image and the code sequences in the watermark extraction phase, and therefore, improve the robustness and message capacity of the watermarking scheme. We give the impl... View full abstract»

    In existing Augmented Reality (AR), data gloves or markers are used for smooth interactions between objects and backgrounds. This results in inconvenience in use and reduced immersiveness. To reinforce immersiveness in AR, added input devices should be removed. To this end, spatial coordinates should be accurately perceived even when a marker has been attached. In this paper, an object expression ... View full abstract»

    In this paper, we improve the convergence prevented from vibrating decision boundary with bias term and suggest a linear activation function. We propose an enhanced fuzzy single layer perceptron which reduces the learning time introducing the rate of learning and the concept of momentum. We applied to Exclusive OR problem and pattern recognition of letters to analyze the performance of learning th... View full abstract»

  • An Effective and Efficient Indexing Scheme for Audio Fingerprinting

    Publication Year: 2011, Page(s):48 - 52
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (350 KB) | HTML iconHTML

    An audio fingerprint is a content-based compact signature that summarizes an audio recording. A song can be recognized by matching an extracted fingerprint to a database of known fingerprints. Audio fingerprinting must solve the two key problems of fingerprint extraction and database search. In this paper, we are given a fingerprint database of songs and focus our attention on the problem of effec... View full abstract»

    Automating the annotation process of digital images is a crucial step towards efficient and effective management of this increasingly high volume of content. It is, nevertheless, an extremely challenging task for the research community. One of the main bottle necks is the lack of integrity and diversity of features. We solve this problem by proposing to utilize 43 image features that cover the hol... View full abstract»

    Visual codebook based texture analysis and image recognition is popular for its robustness to affine transformation and illumination variation. It is based on the affine invariable descriptors of local patches extracted by region detector, and then represents the image by histogram of the codebook constructed by the feature vector quantization. The most commonly used vector quantization method is ... View full abstract»

    Mobile devices have become a new way to access information and consume services on the Internet everywhere. This mobile environment is quite different from a desktop one (e.g. the screen is smaller, lower computing power, the user is usually on route while consuming services), so the requested information has to be customized in order to increase the satisfaction of the users and fulfil their need...
