Skew estimation is a preprocessing step in document image analysis. It involves two steps skew detection and skew correction. Skew estimation is needed because while scanning the document image a little skew is unavoidable. If skew is present in the document then Optical Character Recognizer (OCR) will identify the script wrongly. In this paper an effective and reliable skew estimation technique using radon transform is proposed. Radon transform will take O(N2M) time to execute for a document image of size N X N and with the skew of M. The proposed technique is tested on 150 document images with skew varying from 1 to 25 degrees. The accuracy of identification is 100% and average time of execution is 2.23seconds.","PeriodicalId":418397,"journal":{"name":"2011 11th International Conference on Hybrid Intelligent Systems (HIS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134148568","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}

However, texture feature itself could not provide an overall description of the diseases. In this paper, we propose Continuous Local Feature (CLH) to diagnose the Bronchiolitis Obliterans (BO) lung diseases in the chest computer tomography images. CLH is based on the continuous combination of histograms of local texture feature, local shape feature, and the brightness feature. Because CLH extracts more information, it has high discriminating power and is able to classify between the BO lung disease and normal lung region effectively. The experimental results in classifying between BO and normal lung region show that CLH achieves 98.15% of average sensitivity whereas Local Binary Patterns and Gray Level Run Length Matrix achieve 73% and 75.8% of average sensitivities, respectively. In the receiver operating curve analysis, CLH archives 0.9 of area under curve (AUC) whereas LBP and GLRLM achieve 0.78 and 0.86 of AUCs.","PeriodicalId":418397,"journal":{"name":"2011 11th International Conference on Hybrid Intelligent Systems (HIS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129360530","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}

There is a variety of methods developed to automatically organize documents based on the knowledge extracted from their content. The management of imprecision and uncertainty is very important to improve these methods. Therefore, this work proposes a method to manage imprecision and uncertainty in document organization, by clustering the documents in fuzzy clusters and extracting cluster descriptors. The proposed method was evaluated and the obtained results showed that this is a promising approach to deal with the problem of imprecision and uncertainty when organizing textual documents.","PeriodicalId":418397,"journal":{"name":"2011 11th International Conference on Hybrid Intelligent Systems (HIS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123071015","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 main motivation is to combine ideas from different fields, that have been partially successful, in order to characterize, shed light and tackle the hardness of robust phoneme recognition. Our experiments were carried out over a subset of phonemes of the TIMIT database and the results show potential of the method in environments of varying degrees in the presence of noise and even competing and surpassing state of the art methodologies found in the literature.","PeriodicalId":418397,"journal":{"name":"2011 11th International Conference on Hybrid Intelligent Systems (HIS)","volume":"44 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127196005","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}

There is currently no such study of the effects of ketum on pyramidal neurons using the patch clamp technique. Our team is interested to study the ability of Ketum alakaloid to block L-type Ca channel in a rat's brain.

Auditory evoked responses of total 16 healthy subjects (8 in each group, low and high education groups) were studied with 2 different auditory stimuli (standard and target stimuli). Upon the stimulus types, event-related responses in the 8Hz–13Hz (‘alpha’) range were distributed mainly in the central (Fz, Cz and Pz) locations. The Low education group had significantly high alpha power at Fz and Cz locations comparing the High education group in the case of standard stimuli, where as remarkable increased alpha power was found in the same group in the case of target stimuli at Pz area.

In this context, methods or techniques for representing fuzzy terms in the form of interpretable fuzzy sets obtained from numerical data are strongly required. Typically, in medical settings, statistical data are available or can be obtained from rough data, in the form of probability distributions or likelihood functions. Until now, no theoretical approach was proposed for transforming a probability distribution into a likelihood view fuzzy set. In this paper, a method is developed which generalizes some existing approaches by giving them a theoretical justification. The method enables the construction of normal fuzzy sets, which can be chosen to have a triangular or trapezoidal shape where lateral edges are adapted depending on the input probability distribution. The method was assessed through its application to a simulated normal probability distribution and to real case study pertaining the classification of Multiple Sclerosis lesions.","PeriodicalId":418397,"journal":{"name":"2011 11th International Conference on Hybrid Intelligent Systems (HIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128770394","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 order to illustrate the proposed algorithm, the state estimation of a Weather Balloon is considered, in which the noises affecting the system are highly non-stationary.
