A lot of statistical experiments have been done on the classification of each gesture. During the experiment, we found a phenomenon that several gestures in the 17 gestures were easily confused. And for the sake of description, we call these gestures as similarity gestures. It is assumed that the test result of convolutional neural network model satisfies the large number theorem from the angle of large data. Therefore, For misjudgment gestures, this paper presents a recognition method based on probability statistics.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"23 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":"121196128","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}

Firstly, a three-phase feature matching model is applied to extract rich and reliable feature matching, in the case of low texture, our line matching and contour matching will compensate for the poor quality of point matching. Then, a structure-preserving warping is performed, by defining several constraints and minimizing the objective function to solve the optimal mesh, with which we obtain multiple affine matrices to warp images. Furthermore, we synthetically consider alignment error, color difference and saliency difference to find the optimal seam for image blending. Experiments both on common data sets and challenging surveillance scenes illustrate the effectiveness of the proposed method, and our approach has outstanding performance when compared with other state-of-the-art methods.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"3 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":"126005358","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}

Unfortunately, the cuts produced by existing methods are not very satisfactory, since their global measurements tend to ignore effects of local features, while their local measurements would enlarge the influences from facet details by error accumulation. We observe that the cuts preferred to by human beings are much more dependent on the overall characteristics of local regions, a kind of intermediate-level features, especially in concave regions. Thus, we present a construct to enhance representation of overall characteristics in concave regions for improving cut initialization in concave regions, and design novel energy functions, mainly by intermediate-level features, for extending cutting lines to be enclosed. Then, based on the obtained closed cutting lines, we perform meaningful mesh segmentation in a bottom-up manner according to application requirements. In comparison with state-of-the-art methods, we can have cuts produced more preferred to by human beings, as shown by the experimental results on a benchmark.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"24 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":"128181800","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}

A preliminary user study was carried out to verify that user gaze behaviors have some specific differences in immersive virtual reality environments compared with that in traditional non-immersive virtual reality environments base on 2D monitors and interactive hardware. Analyzed from the user study result, the user gaze behavior in immersive virtual reality environments is more likely to move their head to let interested object locates in the center of the view, while in non-immersive virtual reality environments the user tends to move their own eyes and only move the avatar's head when necessary. Base on this finding, a quantitative equation is proposed to measure the user's attention in immersive virtual reality environments. It can be used into a quality evaluate system to help designers find out design issues in the scene that reduce the effectiveness of the narrative.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"53 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":"124363840","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}
