Biometrics has long been known as a robust approach for person authentication. However, most monomodal biometrics are proven to exhibit one or more weaknesses. In this respect, evidence reconciliation from different biometric systems (referred to as multibiometrics) has attracted much attention lately. Multibiometric systems combine the information presented by multiple biometric sensors, algorithms, samples, units, or traits. In addition to improving recognition accuracy, these systems are expected to improve population coverage, reduce spoofing and be resilient to fault tolerance of different monomodal biometric systems. Here, we present an overview of the different biometric systems, enumerate the advantages and weaknesses of such systems, and some of the newly introduced biometrics. We then discuss the various sources of biometric information that can be combined as well as the different levels of fusion in a multibiometric system. It is becoming increasingly evident that multibiometric systems will be the technology for person identification in the 21st century.","PeriodicalId":384072,"journal":{"name":"2008 First Workshops on Image Processing Theory, Tools and Applications","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131343507","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}

It is related with the 3D information recovery from a pair of images. Although it has being studied for quite a long time, the stereo vision presents some difficult problems, related to the change of visualization perspective. Among the different problems originated from point of view changes, occlusions and ambiguities have special attention and compose the foundation of stereo problem, named correspondence problem. In the related works, the local techniques are fast, but produce poor results whilst the global techniques produce good results but are very computationally expensive. This work aims to give a contribution to the correspondence problem in stereo matching using a local approach with two strategies as solution to ambiguities and occlusions: the multiresolution analysis with images pyramids and the perceptual grouping weight, called Gestalt Theory in the psychology. The obtained results were closer to the ones generated by global techniques, with the advantage of requiring less computational complexity. The use of Gestalt Theory makes this a modern disparity estimation method, due to this theory has received special attention in computer vision researches.","PeriodicalId":384072,"journal":{"name":"2008 First Workshops on Image Processing Theory, Tools and Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121979228","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 the two approaches presented here, objects are detected at a window level, considering all the pixels included in a given window to decide the presence or the absence of objects in the window. Now, according to the a contrario principle, windows with objects are detected as too exceptional realizations of the model representing the windows without objects. The interest of this latter model, called `naive' model, is that it is generally much simpler than the one representing the variety of objects. Two window-based algorithms are proposed, one using the fact that an appearing object can be characterized by significantly high values in the image representing the difference with a background or reference, and the other one using the fact that objects form clusters of object-labeled pixels. The performance of our approach (two algorithms) has been tested on video scenes respectively acquired outdoors and indoors. Both algorithms have also been compared to alternative detection methods, and they proved their performance Finally, the obtained results on artificial noised images show the high robustness relatively to noise of the proposed two-step detection method.","PeriodicalId":384072,"journal":{"name":"2008 First Workshops on Image Processing Theory, Tools and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130215287","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}
