Since rough segmentation of nodules tends to result in high false positive (FP), the main purpose of this study is to reduce the false-positive of candidate nodules via the clustering and classifying approaches. The proposed scheme consists of three phases: pulmonary nodule identification, training nodules clustering, and testing nodules classification. Firstly, the lung parenchyma is extracted through neighborhood connected technology and masking processing, and by appropriate thresholding processing, the candidate nodules are identified. Then, for improving the performance in the training phase, we utilize the AFCM technology. Finally, the category of each testing candidate nodule is determined by Mahalanobis distance. We validated our method on 35 volumes of chest CT, which is subdivided into 20 training part and 15 testing part, and an approximate false-positive of 2.8 per scan is obtained in our experiment. The preliminary results prove that our scheme is a promising tool for pulmonary nodule detection.","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"41 1","pages":"514-517"},"PeriodicalIF":0.0,"publicationDate":"2015-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88176801","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}

Wan","doi":"10.1109/IHMSC.2015.16","DOIUrl":"https://doi.org/10.1109/IHMSC.2015.16","url":null,"abstract":"Accurate noise level estimation is a very important step for many image denoising and computer vision tasks. So far the key idea of most methods is to separate the noise-free image part from noisy images and then use the noise part to estimate noise level. But the noise part usually still contains some image content, which often causes biased estimation results, especially in the low noise situation. In this paper, we propose a novel noise level estimation method. This method first uses the DCT basis to approximate the noise-free image part, then uses the ?2 distribution to approximate the local noise variance. Contrary to the conventional idea that the noise residual approximation can not produce accurate estimates, we show that because of the good approximation capability of the DCT basis for natural image content and the ?2 distribution approximation used in the statistical inference, it is possible to achieve more accurate image noise estimation results than most sophisticated state-of-the-art methods especially at low noise level which is more meaningful. Experiments results confirm the advantages of the proposed approach.","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"36 1","pages":"387-390"},"PeriodicalIF":0.0,"publicationDate":"2015-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81371257","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}
