Various schemes have recently emerged which take advantage of video specific properties for information hiding, most notably through the use of motion vectors. Although many steganographic schemes have been proposed which exploit several possible steganographic domains within video sequences, few attacks have been proposed to combat such schemes, and no current attacks have been shown to be capable of defeating multiple schemes at once. In this paper, we will further expand upon our proposed Discrete Spring Transform (DST) steganographic attack. We will explore further applications of the transform and how it may be used to defeat multiple steganographic schemes, specifically current video steganography schemes. The effectiveness of the proposed algorithm will be shown by attacking a multi-dimensional steganographic algorithm embedded in video sequences, where the scheme operates in two different dimensions of the video. The attack is successful in defeating multiple steganographic schemes verified by determining the BER after DST attack which always remains approximately 0.5. Furthermore, the attack preserves the integrity of the video sequence which is verified by determining the PSNR which always remains approximately above 30dB.","PeriodicalId":440373,"journal":{"name":"2013 IEEE International Conference on Signal and Image Processing Applications","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121565189","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}

Video cartoonization or stylization is the process of artificially incorporating cartoon-like effects to photorealistic input videos. This paper investigates the effects of integrating relevant pre- and post-processing tasks to significantly improve the quality of cartoonized videos processed with bilateral filters (BF). Our video cartoonization framework work extends the original Winnemöller's real-time video abstraction framework, which applies the edge-preserving BF with additional use of edge maps, luminance quantization and frame temporal coherency. In our work, we propose a contrast enhancement option by intensity stretching and Laplacian filtering to finetune the contrast levels of the pre-BF frames. For the post-BF recombined frames, an unsharp masking procedure is proposed to accentuate feature details in the final output video. Results from extensive experiments conducted by qualitative user evaluation underline the essentiality of pre- and post-processing tasks for improved video cartoonization.","PeriodicalId":440373,"journal":{"name":"2013 IEEE International Conference on Signal and Image Processing Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115152966","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}
