In this paper, on the basis of analyzing the principle of the statistics shifting algorithm, a novel robust loss less data hiding algorithm based on region selection is proposed. The proposed scheme divides a cover image into a number of non-overlapping sub regions, and then, uses image gray level co-occurrence matrix to calculate the complexity of each regions. Finally, the secret information is embedded into the optimal sub region, which is measured by the complexity. Experimental results show that the proposed algorithm has a good performance in terms of visual quality and robustness. Compared with the previous algorithm, the PSNR of proposed scheme increases 4.55 dB, and the survival bit rate decreases of 32%.","PeriodicalId":425822,"journal":{"name":"2013 Seventh International Conference on Image and Graphics","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122289785","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}

The CT tracker has been proven to be effective. However, since it does not discriminatively consider the sample importance in its learning procedure, the CT tracker may detect the less important positive samples and, therefore, suffer from drift. In this paper, we present a novel Weighted Compressive Tracking (WCT) model based on the CT tracker. The proposed WCT tracker integrates the sample importance into an efficient online learning procedure so that the features are much more discriminative. Experimental results on challenging benchmark image sequences demonstrate that the proposed WCT tracker performs more favorably than the CT tracker. In addition, the WCT and CT trackers are also applied to the video acquired by the fisheye lens, the result of WCT tracker is very promising, whereas the CT tracker fails.","PeriodicalId":425822,"journal":{"name":"2013 Seventh International Conference on Image and Graphics","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122965076","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}

It has no intrinsic limitation but adequate freedoms for shape adjustment and optimization. The given n-sided hole is filled by rotating a cubic Bézier curve C around a fixed unit vector nc at a fixed center point c of the hole. C's two end points fall on the hole boundary and c respectively. nc is C's normal at c. In this way n triangular surfaces are generated in G0 contact. Then each crease between two adjacent triangular surfaces is smoothed by sweeping another cubic Bézier curve along the crease. Thus n leafy blending patches are produced to replace the overlapped parts of the triangular surfaces. The proposed algorithm is applied to some typical examples of hole-filling on free-form surfaces, such as blending and decoration.","PeriodicalId":425822,"journal":{"name":"2013 Seventh International Conference on Image and Graphics","volume":"292 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123043385","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}

The experimental results demonstrate that the proposed method not only keep abundant details of the background, but also improves the contrast and detect ability of the target object.

Accurate segmentation of juxta-vascular nodules and ground glass opacity (GGO) nodules are an important and active area of research in medical image processing. At present, the classical segmentation algorithm of pulmonary nodules can not accurately obtain the boundary information of pulmonary nodules. In order to solve the problem, a new segmentation algorithm of pulmonary nodules using Fuzzy clustering based on coefficient of curvature is proposed in this paper. Because the coefficient of curvature can effectively distinguish between pulmonary nodules and surrounding structures, and Fuzzy clustering algorithm is adopted, the boundary information of pulmonary nodules can be accurately obtained.
