In this work, we propose a novel biometric hashing method based on optimal linear transformation. This optimal linear transformation is based on the within class covariance matrix and is used for dimension reduction in the proposed biometric hashing method. The proposed biometric hashing method can be used as a biometric verification system. The simulation results show that the proposed method has better performance in comparison with the proposed biometric hashing methods in the literature.","PeriodicalId":114797,"journal":{"name":"2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU)","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121505453","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 method constitutes a touch-less data entry system that is based on the interaction between the magnetic fields around a device and a magnet. The magnetic field that surrounds the device is generated by a magnetic sensor (compass) that is embedded in the new generation of mobile phones. The movements of a permanent magnet in front of the device deforms the sensor's original magnetic field pattern whereby we can constitute a new means of communication between the user and the device. Thus, the magnetic field encompassing the device plays the role of a communication channel and encodes the hand-movement patterns of the user into temporal changes of the sensor's magnetic field. In the back-end of the communication, an engine samples the momentary status of the field during a trial and recognizes the user's pattern by matching it against some pre-recorded templates. The proposed method has been tested in a variety of applications (such as micro-interaction, handwriting recognition, user authentication, etc) and concluded in very promising results.","PeriodicalId":114797,"journal":{"name":"2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126361114","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}

By the use of the proposed technique, the high-rate Golden codes and various WiMAX codes can be efficiently decoded with the optimal ML detection. In the sphere decoding algorithm, 8 dimensional search tree for 2 × 2 Golden code can be separated into 2 semi dependent, 6 dimensional sub trees. For the recommended X4 code in the WiMAX systems, 4 semi dependent, 5 dimensional sub trees can be obtained. By the proposed method, the computational complexity of the sphere decoding can be reduced by about %80 and the speed of the decoding can be increased about 5 times.","PeriodicalId":114797,"journal":{"name":"2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126219257","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 have high recognition performances even in these situations. In this paper, a study to increase the recognition performance of Singular Value Decomposition (SVD) based Common Matrix (CM) method, proposed to recognize when the training set has single image, is done. In this study, Combined Common Subspace Method which combines both global and local features of the face is used. The global features are obtained from the whole face image, while local features are obtained from eyes, nose and mouth. The experiments performed on the Ar-Face database show that using the combined common subspace in the SVD based Common Matrix method increases the recognition performance. This increment especially occurs more significantly in the databases containing facial expression differences more significantly.","PeriodicalId":114797,"journal":{"name":"2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122277159","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}
