In the proposed method, an adaptive threshold of BDM is introduced to determine the required search directions in order to escape from being trapped into a local minimum BDM for the purpose of adjusting the search speed and matching probability. The estimated motion vector will be refined at each search step until the searching process is stopped. Experimental results show that the proposed MFHS algorithm can achieve an average matching probability up to 98% near to that of FS and about 10 times of checking points faster than FS in most of real-world sequences, especially for horizontal-motion-biased image sequences.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127986362","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}

Our algorithm first restores cover image by restoring filter. Then the embedding process is simulated in both test and cover images for certain times and the statistic in local DCT block is calculated as a criterion for classification. Secondly, we propose a region estimation algorithm to estimate the most likely stego regions. Our experiment result is promising by showing hits over 90% and false alarm lower than 10%.

A watermarking scheme that searches for perceptually redundant signal space for embedding transparent watermarks in color images is presented. The search is performed in the wavelet domain of the host color image. A color visual model based on the uniform color metric of the CIEDE2000 color difference equation is used to measure the perceptual redundancy inherent in each wavelet coefficient of various color spaces. Binary watermark signals are repeatedly embedded in qualified wavelet coefficients by the way of quantization index modulation. The watermarking schemes using the uniform and non-uniform color spaces for hiding watermarks are conducted to compare the robustness of the embedded watermark. Experimental results of the analysis show that the non-uniform color space can provide a certain part of color signals a large amount of perceptual redundancy for hiding high-strength watermark signals. The watermark embedded in the non-uniform space is always robust than that embedded in the uniform space.","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":"130318502","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}
