In this paper, we introduce a correlation measure for exploratory analysis based on maximal information coefficient. First, we briefly introduce the traditional data analysis methods and features, expound the necessity of exploring analysis and content. Then, correlation measurement which used commonly are expounded, summarized their characteristics and models. Therefore, we propose a weighted measure based on Maximal Information Coefficient to improve effectiveness of exploratory analysis. Then we get eigenvalues of the Maximal Information Coefficient and Pearson correlation coefficient in linear and nonlinear function of plus noise. Finally, explore analysis display visualization of the results by test dataset, emphasis direction of further research.","PeriodicalId":184905,"journal":{"name":"2016 8th International Conference on Information Technology in Medicine and Education (ITME)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117129574","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}

Automated HE image processing remains challenging because forms and distributions of cells and other tissue structures are always extremely irregular with no clear boundaries, especially in conducting high throughput analysis which demands higher accuracy and efficient quantification for the reference of pathologists. To solve this problem, we proposed an automated quantitative image analysis pipeline based on hierarchical clustering of local correlations, which segmented the image into nuclei, cytoplasm and extracellular spaces by classifying image pixels on the basis of local correlation features. Segmentation for precise nucleus boundaries was then performed, and finally a set of indicators characterizing tissue structures were extracted to complete quantification of HE images. Experimental results showed high accuracy and adaptability in cell segmentation despite data variance. Quantitative indicators obtained in this essay provide a reliable evidence for the analysis of HE staining lymphoma pathological image.","PeriodicalId":184905,"journal":{"name":"2016 8th International Conference on Information Technology in Medicine and Education (ITME)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131459244","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 method improves the original median filter by designing a suit of directional templates. In order to obtain local directions, a filter, which combines Gaussion blur with direction parameter, is designed. Then, directional templates based on local directions mentioned above are used as the filter for reducing spark noise. At last, the finial denoising result of each pixel is obtained from the filtered image or the original noise-polluted image by judging their differences. If the difference between two corresponding pixels of the two images is less than a threshold, the current pixel value of the noise-polluted image is kept. Otherwise, the one of the filtered image is used. The proposed method preserves the contour and the texture areas, which increases visual effects. Experiment results show the proposed method achieves sound performance on the synthetic images created by Field II.","PeriodicalId":184905,"journal":{"name":"2016 8th International Conference on Information Technology in Medicine and Education (ITME)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131936682","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}

In traditional optimization method, the maximum number of shim-piece is set into a same constant. But, in this paper, the maximum number of shim-piece is determined according to its position and the requirement of magnetic field uniformity. By the comparison of these two methods, this method can obtain the better optimization result which has smaller error with the accurate calculation of the magnetic field uniformity. The numerical simulation of the open 1.5T permanent nuclear magnetic resonance(NMR) also verified this point. However, this method is not only suitable for conventional NMR magnet, but also, it can be applied to any other magnets.","PeriodicalId":184905,"journal":{"name":"2016 8th International Conference on Information Technology in Medicine and Education (ITME)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132193796","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}

TCM medical records obtained from Guangdong Provincial Hospital of Chinese Medicine are segmented to single word and labeled with five labeling features(words in sentence, grammatical property of words, words in clinical dictionary, set phrases acting on neighbor context, and set phrases acting on far distance.), and divided into training sets and testing sets. Training sets are also handled with outputted labeling (labeling of symptoms or signs, TCM diagnosis, TCM syndrome type, Chinese medicines (drug), and Names of TCM prescriptions.). In order to evaluate abilities of labeling features on improving clinical terms recognition with CRF, three indicators (recognition Precision (P), recognition Recall (R) and F-score (F)) are defined, and three comparisons are given: comparisons of individual labeling features, comparisons of combined labeling features, and comparisons of combined features in different diseases. The results show that, \"grammatical property of words\" is the best labeling features in all individual labeling features. Multi-combined features have higher scores than individual labeling features on improving clinical terms recognition. The combined mode of \"grammatical property of words\", \"words in sentence\", and \"words in clinical dictionary\" may be the most suitable labeling features. Multi-combined labeling features can improve term recognition with CRF model for text mining in TCM medical cases.","PeriodicalId":184905,"journal":{"name":"2016 8th International Conference on Information Technology in Medicine and Education (ITME)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127535781","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}
