Firstly, an improved Sobel algorithm combined with fuzzy theory is presented, which is used to extract the cerebral information of serial images and can solve the contradiction between preservation of detail information and high de-noising ability effectively. Then, an improved ray casting volume rendering algorithm based on fusion segmentations is used to improve the rendering speed with a better rendering quality. The experiments show that the presented new method can preserve more complete blood vessel 3-D information and obtain good de-noising effect. This new method can produce better rendering quality and speeds up the volume rendering.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117296244","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 a key technique, medical image processing plays an essential role in computer assisted diagnosis. However, most pattern discovering methods focus on human structure images as CT, MRT while very little work has been done in micrograph. In this paper, we proposed a set of simple statistical operations to detect accompanying pattern in micrograph. The samples of different tissues are compared from both spatial distribution and growing direction to check if they fit in the same pattern. The main purpose of this research is to help cancer expert analyze the cause of cancer. Taken breast cancer as experimental case, our results illustrated the accompanying pattern between blood vessels and dead cells.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116201801","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}

Collaborative filtering is the mainstream type of recommendation algorithms, and its core is calculating the similarity between users or items based on ratings. Researchers recently found that the binary similarity based solely on who-rated-what rather than actual ratings output more accurate recommendation. We, from robust perspective, evaluated the binary collaborative filtering under multiple types of profile injection attacks on large dataset. Experimental results show binary collaborative filtering is more robust than actual ratings based collaborative filtering in all situations.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114763224","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}

To improve its scientific degree, optimization problem of GBSO for smelting charges in refined copper strip producing by artificial immune algorithm (AIA) is studied. The multi-objective optimization model for GBSO of smelting charges is established with the objectives which includes minimizing fluctuation in ingredient ratios between the nearest neighbor charges, meeting order priority requirement as much as possible, insuring order due date as much as possible, maximizing number of same brand charges and sorting order in continuous way for same order as much as possible. Some constraints are adequately considered, which includes order due data of each charge, sorting order limit for the charge with high quality requirement, sorting order limit for the charge with the high ratio of virtual orders, sorting order limit for the charge including multi-order, sorting order continuously for same brand charges, ingredient ratio limit for the charge which is sorted order as the first charge, ingredient ratio difference limit between each two nearest neighbor charges. To solve the model in easy way, some constraints are transformed into the objective function, and AIA is designed. The detail steps of AIA is designed in detail including antibody representation and encoding, affinity calculation, clone selection, antibody population updating. To validate the validity of above model and AIA, select practical typical GBSO problem of smelting charges as application instance. Application result shows that, the obtained optimal solution is better than that by heuristic method both on diversity and optimization degree. AIA is suitable for solving complex problem with requirement on solution diversity.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127626909","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}
