Beginning from well known techniques applied to room equalization issues, a frequency domain algorithm that combines fractional octave smoothing of measured impulse responses (IRs) in multiple locations is developed. The IRs are calculated using well positioned microphones inside a car taking into account the properties of the environment. Several results are presented considering different methods to combine the IRs and confirming the validity of the approach in comparison with single point equalization.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117181538","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 recursive filter pair is used as a complementary model filter pair, whereas the masking filters are linear-phase FIR filters. Efficient realization structures for the analysis and synthesis filter banks consisting of all-pass sub-filters and polyphase components of masking filters are derived. The resulting analysis/synthesis filter bank satisfies the all-pass and the nearly perfect magnitude reconstruction properties. It is shown in the paper that by making use of the two-channel filter bank and the two-stage FRM-approach, very sharp filters with nearly linear phase can be achieved. The performances of the analysis/synthesis bank are demonstrated by means of example. An example is also used to illustrate the application of the two-stage FRM-based filter design.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126056805","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 important to find such features which have high ability for discrimination of diverse classes and to get rid of features which are useless for such discrimination. In this paper we propose a new method for feature subset selection utilizing a convex hull (or convex polytope). The method searches for feature space subspaces in which vectors of one class are surrounded by vectors of the other class. The method is applied for selection of color and texture descriptors of capsule endoscope images. The study aims at finding a small set of descriptors for detection of pathological changes in the gastrointestinal tract. The results are compared with results produced by a Radial Basis Function Network classifier.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125490105","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 method, the iris is divided in sub-regions, using locally sliding windows, to extract local signatures. Local distances are then calculated and fused, based on a weighting average. The sliding allows to compensate for local distortions due to segmentation imprecision. The applied weights take into account additional knowledge about the information quantity carried by the different sub-regions and its reliability. Tests have been conducted on the CASIA-IrisV3-Interval database. They show good performances of the new method. Similar or even better results are obtained, compared to published ones, with a set of iris containing twice more subjects.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"93 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129418863","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 this paper we propose such a system, where a novel interface gives the user the opportunity to visually and interactively explore the feature space around relevant images and to focus the search on only those regions in feature space that are relevant. When an image is explored, its optimal set of feature weights is automatically determined using all images contained within the relevant regions, based on the evidential support for the relevance of each single feature. Images are ranked twofold, where one ranking reflects the likelihood the image is useful for further exploration of the feature space and the other reflects the likelihood the image is relevant to the user.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129507860","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}

Use of acoustic signatures of Internal Combustion (IC) engines for the condition monitoring procedure is the basic motivation of this paper. Acoustic signatures of IC engines always carry relevant information. However, in many cases, these acoustic signatures might be corrupted by the surrounding noise resulting in a low signal-to-noise-ratio (SNR). Extracting features from the signals having low SNR becomes highly difficult. Therefore, those signals corrupted by noise should be preprocessed before extracting features from them. In this paper, a denoising method based on empirical mode decomposition (EMD) and Morlet wavelet is presented. This denoising method is an advanced version of ldquosoft thresholding denoising methodrdquo proposed by Donoho and Johnstone and ldquogeneralized soft thresholding methodrdquo proposed by Jing Lin. Morlet wavelet based denoising eliminates the noise and improves the SNR significantly and Back Propagation (BP) is used further for classification of faulty and healthy IC engines. Results obtained by using these techniques for condition monitoring of IC engines are promising.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128474962","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}

We describe a framework for image annotation watermarking, especially Nested Object Annotation Watermarking. This was introduced in earlier works to embed not only textual and/or semantic descriptions as annotations but also their relationships with each other. The framework describes in a formalized manner how to deal with annotations, overlapping multiple watermarks, and how to express semantic relationships between the annotations. Based on this, our watermarking algorithm is presented, extended by support of image hashing and cover pre-conditioning. Further, we present three application scenarios: annotations for technical manuals, digital long-term preservation and medical images. For these parameter recommendations are derived.","PeriodicalId":382753,"journal":{"name":"2009 Proceedings of 6th International Symposium on Image and Signal Processing and Analysis","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123212990","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}
