According to linear relationship of the decay linewidth distribution coefficients and exponential terms of autocorrelation function (ACF), a new inversion algorithm combining linear and nonlinear estimation is proposed. By changing four parameters optimization problem into two parameters optimization problem in turns, new algorithm improves the inversion accuracy and reduces two initial parameters. By new and tradition algorithm, ACF of 200nm – 600nm bi-dispersed particles is respectively inversed. For noise-free ACF, inversion error of new algorithm is 0, which is at least better than tradition algorithm 2.01%. For inversion of noise ACF, compared with tradition algorithm, new algorithm can reduce inversion error by 0.93% ∼ 6.43%. Therefore, new algorithm is superior to tradition algorithm in inversion accuracy and tolerance of noises.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"274 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116627466","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}

Following discussion on the advantage and disadvantage of curvelet and wavelet transforms based SAR images despeckling, an algorithm which combined curvelet and wavelet transforms was proposed for despeckling of high resolution SAR images. Firstly, the curvelet and wavelet were used to denoise the original SAR image, then the related residual image between their results was acquired, which was then denoised through the curvelet transform. Finally the denoised residual image was added to the curvelet denoised image. Experimental results of TerraSAR-X high resolution images indicated that, compared with the Enhanced Lee filter, the Enhanced Frost filter, the wavelet transform based and curvelet transform based methods, the algorithm presented here had well despeckling effect, as well as fine edge-preserving ability.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116750504","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}
