    Publication Year: 2007 , Page(s): xliii - xlv
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (107 KB) |  | HTML iconHTML  

    WIMAX is predicted to be a serious competitor to existing wireless systems (WLL, LMDS, GSM, UMTS), offering an advanced air-interface and all-IP architecture, which implies more complex network design and deployment. This tutorial aims to provide a design process and generic methodology that can be applied in different WIMAX deployment scenarios. The presentation of the methodology will be structu...

    The tutorial presents an overview of the techniques currently used for mobile localization. First, a brief overview of the location based services and the localization systems and techniques, currently in use, is provided. Then, the focus will be on the localization techniques based on the TOA (time of arrival) and AOA (angle of arrival). In particular, we will discuss the main issues of NLOS (non...

  • Contour Image Indexing using Dyadic Wavelet Transform of One Dimensional Signal with Branch Compensation

    Publication Year: 2007 , Page(s): 1 - 4
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (4426 KB) |  | HTML iconHTML  

    Various methods exist for the indexing of images. In this work we represent an image by a 1D signal. From this 1D signal we extract the features using wavelet transform to index the images. The 1D representation of the contours would help to decrease the computational complexity of processing the 2D signal, thereby increase the speed of the process. In order to represent a 2D image in terms of a 1... View full abstract»

  • Unsupervised Elimination of Media Items in Content-Based Image Retrieval

    Publication Year: 2007 , Page(s): 5 - 8
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (4207 KB) |  | HTML iconHTML  

    A novel unsupervised method for elimination of irrelevant media items for retrieval is presented. The proposed method aims to decrease retrieval complexity and memory consumption of content-based indexing and retrieval systems. The method is suitable for layered systems that iterates query process more than one time to improve and/or refine the query results. The elimination is performed on the qu... View full abstract»

    The focus of this paper is on automatic annotation for semantic image retrieval. This work is aimed at identifying visual descriptors that are most relevant, effective and suitable for semantic annotation tasks. We propose an image annotation system based on support vector machines and a combination of descriptors that includes a gradient direction histogram and several MPEG-7 visual descriptors. ...

  • Effects of Arbitrary-Shaped Regions on Texture Retrieval

    Publication Year: 2007 , Page(s): 13 - 16
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2800 KB) |  | HTML iconHTML  

    Texture is a widely used feature in content- and region-based retrieval systems. Most studies focus on texture extraction over an entire image or use color-texture combinations for region-based retrieval. Less attention has been drawn towards texture extraction and its evaluation over arbitrary-shaped regions. In this paper frame-based and region-based texture extraction schemes are compared to ev...

  • A Novel Finite Mixture Model for Count Data Modeling

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (773 KB) |  | HTML iconHTML  

    In this paper we examine the problem of count data clustering. We analyze this problem using finite mixtures of distributions. The multinomial and the multinomial Dirichlet distributions are widely accepted to model count data. We show that these two distributions cannot be the best choice in all the applications and we propose another model based on the selection of the generalized Dirichlet as a... View full abstract»

    Skin detection represents a challenge in recent years, due to the fact that imaging conditions and illumination factor affect the resulted image. In addition, human skin color has a wide range making it a tedious task to target and extract. This paper addresses a novel method to detect skin in still images. The detection approach is based on five face detection models with integral modifications t... View full abstract»

  • Relay Cyclic Delay Diversity: Modeling & System Performance

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1945 KB) |  | HTML iconHTML  

    A cooperative communication scheme referred to as relay cyclic delay diversity (RCDD) is presented in this paper. The scheme is based on a set of distributed relay nodes (RNs) with each node associated with a certain cyclic shift in order to generate artificially multi-path diversity and equivalently frequency diversity. RCDD is an open loop scheme and the user terminal (UT) only needs to estimate... View full abstract»
