Using prior knowledge and parameterized feature template for given objects, our method combines global matching/ morphing with hierarchical part-based approximation. The method starts from construction of parametric templates associated target object. Through contour detection preprocessing and template retrieval, we obtain the exact morphable feature template. Combining edge-oriented contour detection, corner detection and local prior template, the exact endpoints and curve segments are obtained. Finally, the segmented parametric feature lines are automatically fitted using cubic B¡äezier curves. Taking car body design as numerical examples, we establish the corresponding database. Numerical results show that our method is effective to abstract the design features with high precision for car styling.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126785378","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 paper introduces a method merging with mean value coordinates. The method firstly computes the mean value coordinates of the vertices in the source mesh with respect to its boundary. After specifying the difference between the two mesh's boundaries, it interpolates the difference of the source's inside vertices through the coordinates, and then constructs a new mesh to merge. With the same framework, smoothing the seaming line can be achieved by interpolating tangent vector variations. This method avoids the mesh parameterizations or the solving a large linear system, but does merge through computing close form expressions. Experiments show that mesh merging with this method is less artifacts and faster, comparing to the method through solving Poisson equation.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128588069","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}

Experiment results show that the proposed hybrid algorithm for feature selection increases the testing accuracy of classification. The combination of the feature sets extracted is likely to improve the performance of general steganalysis methods which have more practical value for deterring covert communications and the uncorrelated features extracted contain more discriminatory information when distinguish different kinds of steganography.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126704054","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}

These two properties make NCC outperform the previous differential coordinates in many mesh processing jobs. We develop a novel deformation algorithm based on NCC, which is efficient by subtly using vertex normals. In addition, since NCC have no tangential drift and are well defined on boundary, they can be easily extended to industry applications, such as automobile modeling. Experiments show that NCC perform better than the previous differential coordinates in both effectiveness and efficiency.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133585369","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}

However, the study of recognition and enhancement of the specific target for the computer generated image is very less. Compared with the natural image, this cause may be the characteristics (simple in overall) and the scene of applications (the 3D roaming, the game and so on) for the computer-generated image. For recognition and enhancement of the specific target (such as traffic sign) in the computer-generated image, the difficulty is how to accurately recognize and enhance the specific target, and maintaining other information of object do not been changed. In this paper, adopting stepwise refinement method attempts to solve the problem. The proposed method is based on three steps including image preprocessing, image recognition and enhancement. The experimental results show the method can be very good to deal with such issues. The research result shows that the image recognition and image enhancement is still not simple process. Therefore, we imagine that image recognition for complex real scene image also isn't simple issues.
