In this paper, a digital image watermark algorithm operating in the curvelet domain is proposed. Unequally-Spaced Fast Fourier Transforms (USFFT) is employed to implement Fast Discrete Curvelet Transforms (FDCT ) to transform the digital image to the curvelet domain. The following three factors are considered when embedding the watermark in the curvelet domain: (1) the scale distribution of the curvelet coefficients; (2) the variation of high frequency components and low frequency components have different effects on HVS; (3) the impact of the variation of the curvelet coefficients on the robustness of the watermark. Combining these factors with the basic watermark algorithm, we choose the proper position to embed the watermark. The experimental results demonstrate a fine unification of robustness and invisibility and shows advantages over watermark algorithm in the ridgelet domain concerning the two aspects.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126322211","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}

First, the rate-distortion (RD) relationship with respect to subpel MVs is examined to shed light on the tradeoff of R-D performance degradation and complexity reduction in different block types. It is observed that the R-D gain of some macroblocks (MB) is greatly enhanced by employing subpel MVs while others are not. An SAD-based approach is adopted to decide whether the subpel MV scheme is needed for a certain MB. To enhance the prediction accuracy, the correlation of MVs in the spatial domain is also exploited. Our scheme further introduces decoder complexity budget to aid the designer in making design tradeoffs. Experimental results indicate that our scheme is flexible enough that the actual achieved complexity is very close to the target complexity budget under different QP settings.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114296015","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}

Besides, we also propose a scheme of integrating adaptive intrarefresh into the proposed MHMCP coder to further improve the error recovery speed. Extensive simulation results show that the proposed methods can effectively and quickly mitigate the error propagation and the penalty on coding efficiency for clean channels due to the inserted error resilience features is rather minor.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116963880","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 detecting a watermark, there are two kinds of detection errors, a false positive error (FPE) and a false negative error (FNE). A detection scheme is said to be optimum if the FNE probability is minimized for a given FPE probability. In this paper, we present an optimum detection scheme for additive watermarks embedded in the spatial domain. The key idea of the proposed detection scheme is to use the difference between the brightness values. It is confirmed experimentally that the proposed scheme can control the FPE probability strictly.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"1999 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123550239","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}

During the detection, the embedded watermark will be extracted based on the fast correlation attacks technique. Owing to its powerful error-correcting capability, the robustness against both geometrical distortion and common signal processing can be readily obtained.
