In this study, in order to improve the voice recognition accuracy in real world source separation, a new method that uses Independent Component Analysis (ICA) in the time-frequency domain using the variable density complex discrete wavelet transform (VD-CDWT) and the subspace method has been proposed. Through comparison of the results according to signal noise ratio (SNR), the effectiveness of the proposed method is confirmed.","PeriodicalId":424264,"journal":{"name":"2009 International Conference on Wavelet Analysis and Pattern Recognition","volume":"162 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116636164","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 works by modeling the relationship between the wavelet coefficients interscales. For the discrete wavelet transform (DWT) has its own drawbacks inherently, such as shift variance, lack of directionality, etc. The traditional HMT model based on DWT often leads to an unideal segmentation result. Because of the near shift-variance and good directional-selectivity of complex wavelet transforms, here the authors proposed a complex wavelet domain HMT model (C-HMT) to improve the accuracy of multiscale classification results. To get an accurate final segmentation, labeling tree model was used to fuse the interscale classification results. In the experiment, the classification and segmentation results of the proposed method are found to be better than the traditional wavelet-based models.","PeriodicalId":424264,"journal":{"name":"2009 International Conference on Wavelet Analysis and Pattern Recognition","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117181931","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}

HIS (Intensity-Hue-Saturation) transformation is one of the most commonly used method which fusing those two kinds of images, however, the traditional IHS transformation method faces a severe problem namely color distortion. In this paper, we first review several improved IHS transformation image fusion algorithm, and then proposes a new IHS fusion method based on region standard deviation, which fuses the low-spectral/high-spatial resolution images and the Intensity component of the high-spectral/low-spatial resolution multi-spectral image based on region standard deviation. Further, we improve this image fusion rule in wavelet field. The experiments show that this new proposed image fusion method can effectively provide richer information in the spatial and spectral domains simultaneously.","PeriodicalId":424264,"journal":{"name":"2009 International Conference on Wavelet Analysis and Pattern Recognition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125498980","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}

This paper proposed a new fusion algorithm based on wavelet transform and canny operator to detect image edges. In the wavelet domain, the low-frequency sub-image edges are detected by canny operator, while the high-frequency sub-image are detected by solving the maximum points of local wavelet coefficient model to restore edges after reducing the noise by wavelet. Then, both sub-images edges are fused according to certain rules.
