HSICT can be accomplished in a process of three steps: (1) Illumination color estimation is achieved by using two different color distributions; (2) A linear transform is applied to eliminate the influence of highlight; (3) The effect of shading is removed by normalization. Experiments illustrate that HSICT can not only effectively remove highlight and shading in color image, but also can be easily combined with other algorithms in many fields, such as segmentation and edge detection.","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":"115137967","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}

As first, we decompose the image using the contourlet transform. Then the features of the lowpass subband and the bandpass directional subbands are extracted respectively. Here we use the normalized gray-level co-occurrence matrix and the generalized Gaussian density to extract ear features. Finally, the two kinds of features are connected and the SVM method is used for classification. Extensive experiments have performed to valid its efficiency and robustness. Moreover, we can conclude that for ear feature extraction, the contourlet transform is more suitable for wavelet transform.","PeriodicalId":424264,"journal":{"name":"2009 International Conference on Wavelet Analysis and Pattern Recognition","volume":"27 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":"125088745","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}

Since traditional wavelet transforms are unable to control the noise well and the edge is not consistent with direction properties, some improvements are made and a new kind of wavelet transform is proposed. It detects the edge of original image by means of new wavelet transform and Canny operator respectively, then produces a new image by fusing and analyzing the two results based on the experimental results.
