Performance drops can be detected which trigger an automatic parameter regulation module. This regulation module is an expert system that searches a parameter setting with better performance and returns it to the tracking system. With such an architecture, a robust tracking system can be implemented which automatically adapts its parameters in case of changes in the environmental conditions. This article opens a way to self-adaptive systems in detection and recognition.","PeriodicalId":393875,"journal":{"name":"Seventh International Workshop on Computer Architecture for Machine Perception (CAMP'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126796139","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}

Key performance issues like robustness, adaptability, flexibility and real-time must be pursued together with simplicity of design. These requirements have accentuated the interest in multi-modular systems and data fusion. The literature has proposed two main paradigms of multi-modular fusion: redundancy (or combination) and selection (or switching). We compare the relative advantages and complementary uses of the two paradigms. Then we focus on selection, which seems to attract less attention than redundancy -at least in machine vision, where we operate. After summarizing our work on a selection-based fusion scheme named context commutation, we describe a methodology in ten steps to design selection-based systems. With this paper, we hope to contribute to the understanding of selection as an additional tool for researchers and engineers working on machine perception.","PeriodicalId":393875,"journal":{"name":"Seventh International Workshop on Computer Architecture for Machine Perception (CAMP'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121923036","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 functional based on statistical properties of the image around the scratch is optimised using an ad-hoc genetic algorithm. Given the large amount of computational time needed by genetic algorithms, a network of standard workstations with heterogeneous operating systems has been used. Each workstation in the network works on each scratch to perform the restoration, and a specific machine works as a root node with the task of distributing jobs on the network and adding the outputted restored scratches back into the image.","PeriodicalId":393875,"journal":{"name":"Seventh International Workshop on Computer Architecture for Machine Perception (CAMP'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127426265","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 a space mission that is extremely demanding in terms of computing power and data storage. PLANCK simulations mimic the whole mission starting from a virtual sky (ideal or \"contaminated\" by introducing several noise sources). Most of the related software is already installed at the two Planck DPCs (HFI and LFI). Its main goal is validation of the pipeline modules that will be used to build the data reduction pipelines during the operative phase of the mission. The software can also be profitably used to face the challenging computing power and data storage requirements and also during the pre-launch phase of the mission. Grid, the new technology that enables the distribution and sharing of computing power and data storage capacity over a geographical network, seems to be a promising answer to Planck data storage and processing needs. In the framework of the Italian, LCG based, Grid infrastructure at INFN, we managed to run a number of experiments aimed at defining an application specific environment for the PLANCK simulation software and at distributing on the Grid the produced simulated data. Such experiments have proved that the \"gridification\" of Planck pipelines is not only possible but is extremely convenient in terms of data processing speed and available data storage as is well illustrated in this paper.","PeriodicalId":393875,"journal":{"name":"Seventh International Workshop on Computer Architecture for Machine Perception (CAMP'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116303596","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}
