It is shown that the concept of image utility consists of many aspects including image content understanding, image quality assessment etc. For image content understanding ontological models can be used. In particular, using ontological models based on the concepts of extended algebra of relations is proposed. The general idea is illustrated by simple examples.","PeriodicalId":329519,"journal":{"name":"2007 IEEE International Workshop on Imaging Systems and Techniques","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115296918","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 proposed approach integrates a robust feature extraction technique based on a specific method of eigenanalysis of the unique classes identified in the problem at hand, with neural network based classifiers. Such an eigenaiysis aims at identifying principal characteristics of the above mentioned uniquely identified classes. Each unknown image, in the testing phase, is then, analyzed through a sliding window raster scanning procedure to sliding windows identified, through a first stage neural classifier, as belonging to one of the unique classes previously mentioned. After such a sliding window labeling procedure it is reasonable for a second stage neural classifier to be applied to the testing image viewed as a sequence of such labeled sliding windows for obtaining a final decision about whether a face exists within the given test image or not. Although the proposed approach is a second stage procedure, it is obvious that its most critical phase is the first stage classification process, since, if good identification/ labeling accuracy could be then obtained, it would facilitate final classification stage a lot. Therefore, the experimental section of this paper is conducted with respect to analyzing face specific classes labeling accuracy at such a first classification stage.","PeriodicalId":329519,"journal":{"name":"2007 IEEE International Workshop on Imaging Systems and Techniques","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123933536","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}

Proposed method has been used in scientific projects and we present two practical applications where this system is used and what benefits we get from it. Main part of this study is that how we can make more effective measurement process by using two line scanning based spectral cameras at the same measurement process and how we can combine those spectral cameras' spectra. We also describe differences between common spectral imaging systems. We also represent one of our produced software algorithm which we can use in measurement process.","PeriodicalId":329519,"journal":{"name":"2007 IEEE International Workshop on Imaging Systems and Techniques","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121142135","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 algorithm assumes presence of a training set of example images. From this set a number of image patches is selected. Using sparse kernel feature analysis, the similarity functions for each symbol are prepared. These functions are used to get terminal symbol locations within analyzed image. A list of symbol locations is then reduced into a tree.

Color correlogram extracts not only the color distribution of pixels in images like color histogram, but also extracts the spatial information of pixels in the images. The characteristic of the color correlogram to take into account the spatial information as well as the distribution of color pixels greatly attracts the researcher for content based image retrieval. Even though, a single correlogram is not enough for efficient and robust image retrieval system. In this paper, we propose the use of color correlogram on multiresolution images. The multiresolution color correlogram gives much better retrieval efficiency, but with higher computations. The multiresolution images are generated using the median filters.","PeriodicalId":329519,"journal":{"name":"2007 IEEE International Workshop on Imaging Systems and Techniques","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121243789","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}
