Worse still, those frames which are screened by algorithm can't achieve the requirement of express and the screening process greatly damages the original signal. This paper presents a strategy for screening speech keyframe and designs a screening scheme for key-frames based on the strategy. This scheme refers to the speech's logarithm energy and the weighted-zero-crossing rate. The detail process of screening scheme: firstly, screening frames according to the logarithm energy of the speech signals. Meanwhile, combine the speech amplitude and zero-crossing rate for frames screening. Finally, calculate the similarity of the two screening results, and getting the key-frame set. In addition, the scheme has been analyzed and validated from those aspects like continuity, characterization and applicability, in order to verify the effectiveness and availability. The results illustrate that these frames which have been screened by this scheme have advantages of continuity, characterization etc.","PeriodicalId":199874,"journal":{"name":"2017 IEEE 17th International Conference on Communication Technology (ICCT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127548605","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}

Using SPOIL, users can query routes from POI (Point of Interests) A to POI B, while not revealing the locations of A and B to the map server. Different from previous works, SPOIL is transparent to existing map services, assume no trusted third party, and more efficient for smartphones. The basic idea is simple: the client (i.e., smartphone) shifts user-intended POIs to some neighboring POIs instead, and query the map server using the shifted POIs. By carefully selecting places for shifting, we ensure: (1) privacy: on observing the route query, it is difficult for an adversary to identify the user-intended endpoints. (2) usability: the returned route is very similar to the intended one, thus giving useful directions for the user; To make SPOIL efficient for smartphones, we let clients retrieve candidate places for shifting from an additional server, instead of storing all the places and computing nearest ones locally. We implement SPOIL as an Android application, and evaluate it with real query traces. Experimental results show that SPOIL strikes a good balance among privacy, usability and efficiency.","PeriodicalId":199874,"journal":{"name":"2017 IEEE 17th International Conference on Communication Technology (ICCT)","volume":"324 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132203053","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 human visual masking model of a 3D motion in video sequence is studied in depth. The human eye visual masking threshold is obtained as the maximum embedding intensity of watermark using various motion characteristics. Second, the high- and low-frequency sub-band coefficients of the contourlet field are obtained by contourlet transform. Chaotic watermarking sequence is embedded into the high-frequency sub-band coefficient with the highest energy to increase imperceptibility. Third, when the low-frequency sub-band coefficients has the stability of its coefficient histogram against geometric attacks such as rotation and scaling, the watermark signal is embedded in a low-frequency sub-band histogram of adjacent coefficients to increase the watermark of an anti-geometric attack. Finally, ASIFT is used as a trigger to determine whether the video frame is subjected to geometric attacks or not. For geometric distortions, ASIFT is used to regulate the geometrically attacked video frame. The low-frequency sub-band coefficients of the regulated video frame are used for the watermarking extraction algorithm. The high-frequency watermarking extraction algorithm is used directly for the non-geometric distortions. Experimental results show that the proposed algorithm could guarantee watermark invisibility and favorably extract the watermark for common geometric and conventional signal attacks. The proposed algorithm is a strong video-dual watermarking algorithm.","PeriodicalId":199874,"journal":{"name":"2017 IEEE 17th International Conference on Communication Technology (ICCT)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130862855","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}
