The collaboration allows project participants to work together by sharing information, processes, and common values. On the other hand, free software provides powerful applications ready to be integrated for the construction of applications and internal platforms to the organizations. A platform of collaborative work mainly intended for the development of technical artefacts like software, even if it is initially conceived for the lodging of projects and the management of their development, in practice it is also useful for many types of projects of collaborative work within the institutions where it is deployed. The project of technological exchanges will propose a platform \"ready to use\" which we believe is able to integrate into many environments, including institutions of higher education and research. This platform is realized by integrating a set of free software, to better ensure the scalability of internal applications: forge Libre Source, php Group ware, Wiki, sympa, Web-Dav, OpenLDAP as a component for specific application development.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132324781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal is to automatically make all images to a common frame. Image registration has been used to ensure pixel correspondence to the same tissue location throughout the whole temporal sequence. Best approaches are based on using local information, but they are very sensitive to light change and reflections which are frequently current in colposcopic images. In this paper, we propose an approach less sensitive to these variations, moreover, it works well even if reflections are present in colposcopic images. The efficiency and the robustness of the method for colposcopic images are demonstrated.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124426118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method is then considered as a pre-processing step in a view-dependent progressive coding of 3-D meshes. Our segmentation process aims at producing homogeneous regions which have similar frequency amplitudes on the mesh surface, in other words: patches with different degrees of roughness. As a preliminary step of the development of a locally-based Rate-Distortion (R-D) optimized coding scheme, we propose to study the behaviour of the wavelet decomposition in the created patches, during the coding and the view-dependent reconstruction processes. To our knowledge, no previous work has ever considered the influence of the nonrefined parts of a mesh on the more detailed ones, in a view dependent context. The main contribution of this paper consists in considering three different possible wavelet decompositions, close to the patch borders, and to study their influence during the coding and the view-dependent reconstruction stages. Among these three decompositions, we define a new scheme and finally propose various experimentations to demonstrate that it behaves better than the other classical considerations, for view-dependent reconstruction purposes.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122372950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Gray Level Co-occurrence Matrix, Local Binary Patterns, Wavelet, Ranklet, Granulometry, and Laws’ Masks will be used to extract features from the images. The extracted features are then fed into five classification techniques: Linear and Quadratic Classifier, Neural Networks, Support Vector Machine, and K-Nearest Neighbor so that each class membership can be obtained. The success rate of each method then measured by comparing the predicted labels and its ground truth so that in the end, the best feature extraction method will be indicated by the highest classification rate. This paper provides recommendations in feature extraction method and classification technique which may give good result in similar task. By considering several factors, such as: computational complexity, classification rate, and running time, this work has found that LBP is more appropriate to analyze wood texture.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126170142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Point-sampling techniques allow for high quality reconstruction, but suffer from aliasing artifacts, time-costly to attenuate. On the other side, area-sampling, popularized by Edwin C. Catmull's Unweighted Area Sampling or UAS, is equivalent to point-sampling at an infinite rate, but reconstruction is restricted to a unit-size box-filter, which offers very poor reconstruction characteristics. We propose a new rasterization algorithm named multiresolution integration, MI which provides high quality reconstruction such as point sampling techniques may do, while achieving speed in the range of unweighted area sampling: a weighted average of box filters is used to approximate the convolution integral between the polygon and any kernel of finite extents. A simple and fast implementation is described, providing high quality 2D rasterization at interactive speed. Examples and benchmarks demonstrate both the quality and speed of this new method.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124042789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data sources can be stored in traditional databases and are increasingly available in semi-structured formats, including dynamic web pages, which can be accessed through web forms. To alleviate the inherent heterogeneity and security issues involved in merging data sources, service paradigm, particularly data-providing services, are increasingly used to extract and to share data from various sources. In this paper, we propose a service based environment for dynamically creating applications by extracting and combining data through the composition of data-providing services. Data-providing services are described by generalized tree patterns, which are used to select the sources that are relevant to query processing. We discuss how to select sets of data-providing services to semantically cover the concepts used by an application.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129905974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our stylizations are based on well-known artistic styles ranging from Chiaroscuro to comics. Lighting has always been used in graphical art to give realism to an illustration or to enhance visual contrasts between objects in a scene. This allows creating a global atmosphere. Giving an input image, our model automatically generates a lighting map of the image which may be modified by the user to determine different types of shadows or light effects like highlights. Following graphical arts styles, we propose six stylizations. Our model is flexible and specifically designed to help users and even amateur users, to semi-automatically stylize the different kinds of light effects in an image.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133022852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These issues significantly exacerbate the difficulties involved in the development of flexible and effective visualization solutions. Dealing with such complex problems often requires visualizations to be developed in a manner that they can be flexibly created, instantiated, manipulated, customized, integrated with other visualizations, executed and modified. However, while existing visualization techniques and systems tend to provide reasonable support for particular paradigms, domains and data types, they are quite weak when it comes to addressing such flexibility requirements. To address these issues and requirements, we propose an information generation, representation and presentation (IGRP) approach to support visualization to be designed/modeled/implemented in a flexible manner. This approach is specified and demonstrated through IGRP reference model, framework and architecture that highlight the idea of developing visualizations through manipulating, creating, modifying, enhancing, mapping and integrating the IGRP related data, models, solvers and scenarios. A prototypical system is also implemented and discussed as a proof of concept.","PeriodicalId":128396,"journal":{"name":"2010 Sixth International Conference on Signal-Image Technology and Internet Based Systems","volume":"18 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130391981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In spectrogram representation of a speech signal, after deleting low SNR elements, incomplete spectrogram is obtained. In this case, the speech recognizer should make modifications to spectrogram to restore the missing elements, which is one direction. In another direction speech recognizer should be restoring the missing elements due to deleting low SNR elements before the recognition is performed, which can be done using the spectrogram reconstruction methods. In this paper, some spectrogram reconstruction methods suggested by some researchers are implemented as a toolbox using MATLAB and tested using Sphinx III software under different conditions such as different length of window and different length of utterances. These methods are called clustering statistical methods and tested with Sphinx III software developed by CMU, USA.
