In this context, this paper presents anew 3D line segment extraction method by using disparity map generated in the process of stereo matching. The core of our technique is that feature matching is carried out by the reference of the disparity evaluated by area-based stereo. Since the reference of the disparity can significantly reduce the number of feature matching combinations, feature matching error can be drastically minimized. One requirement of the disparity to be referenced is that it should be reliable to be used in feature matching. To measure the reliability of the disparity, in this paper, we employ the self-consistency of the disparity. Our suggested technique misapplied to the detection of 3D line segments by 2D line matching using our hybrid stereo matching, which can be efficiently utilized in the generation of the rooftop model from urban images.Since occlusions are occurred around the outlines of buildings, we use multi-image stereo scheme by fusing 3D line segments extracted from several pairs of stereo images. The suggested method misevaluated on Avenches data set of Ascona aerial images.Experimental results indicate that the extracted 3D line segments have an average error of 0.5m and can be efficiently used to the construction of 3D site models using a simple 3D line grouping.","PeriodicalId":206267,"journal":{"name":"2009 International Conference on Digital Image Processing","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133789763","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}

Users have to click six times on one point in some given specific regions (pass regions) shown with dotted lines in a theme image displayed on the screen. The selected region is then zoom to create a next image. Exactly, we are not going to zoom the region object of the theme image up to six times; rather we are replacing the image with another image of the same object in big size. The next image is based on the previous click-region. We secure our scheme from shoulder surfer attacking by using WIW scheme with our scheme. We also present the results of an initial user study which revealed positive results. Performance was very good in terms of speed, accuracy, and number of errors in recognizing the images. We can also demonstrate that CTZ provides greater security than Pass Points because the number of images increases the workload for attackers also it is more user friendly and attractive than other competitive schemes. It is just parallel to Cued Click Scheme. It meets the today’s requirement of extremely high security.","PeriodicalId":206267,"journal":{"name":"2009 International Conference on Digital Image Processing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122537599","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}

Leukocyte count is used to determine the presence of an infection in the human body. To be able to observe and recognize the different kinds of leukocyte, you must stain them. For this purpose, normally Giemsa stain is used. There are two difficult issues in image segmentation which common segmentation algorithms can not overcome them. Nucleus which is laid inside white cell is the darkest part of image which can be used to count cells. Since Giemsa staining is done by humans, intensity of images is slightly different from each others. Neutrophils are kinds of leukocytes which have segmented and distinctive nucleus. These reasons cause a considerable error in counting. In this paper, we have proposed to use histogram of images and intensity of red cells which are major objects in images to select appropriate point for thresholding. And then the distances among centers of the extracted nuclei have been calculated, according to the specified size of leukocytes, we merge the nuclei which those distances are less than the diameter of one leukocyte. Experimental results show that our approach is very efficient.","PeriodicalId":206267,"journal":{"name":"2009 International Conference on Digital Image Processing","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132285007","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}
