It also provides a user interface for controlling the level of details. As a preprocessing, CAT first hierarchically clusters images and selects representative images for each cluster. And then, CAT visualizes the tree structure applying a hierarchical data visualization technique HeiankyoView. As a characteristic of CAT, it provides a graphical user interface for the zooming operation to effectively browse images. It selectively displays representative images while zooming out, or individual images while zooming in, by the mouse operation. This feature realizes high frame rates, and display of adequate number of images.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124035843","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}

Images taken at different times are deformed by visceral movement. The deformations are non-rigid deformation. For medical diagnosis using the images, it is desired to develop a non-rigid image registration. In this research, we register two images that are acquired at different time. We have developed a method for non-rigid image registration, where we use a free-form deformation for image alignment, sum of squared difference as our similarity measurement, and a steepest descent method for optimization. The method achieves improved processing speeds with user interaction for specifying deformation areas.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114921698","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 order to quantitatively realize the existence of spiral movement, analysis of a 3 dimensional (3D) time series of a dance motion performed by two master Japanese classical dancers was carried out. It revealed that the transformation of original 3D coordinates into a local coordinate system consisting of principal components, was effective. The first principal component represented the overall direction of body motion, and the spiral motions were clearly visualized through cyclic curves appearing in the second and third components, perpendicular to the first component.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122771670","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}

This paper proposes and evaluates a framework for an image revision management system, which uses the JPM file format to store differential elements between two versions of the image. Two data storing approaches are considered, one stores replaced elements after the edition, and the other stores replaced elements or differential elements adaptively. These approaches are evaluated with four different kinds of edit operations: blurring, edge emphasis, character writing, and adding noise. Since the combination of JPM’s image object organization and JPEG 2000’s efficient region compression is effective for image revision management, our proposed system can save storage capacity and network bandwidth in the image revision management system.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129514494","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}

However, this method has a drawback to increase the computational cost almost linearly to the number of overlapped blocks because DME using OBM allocates multiple motion vectors to a local region in the image restoration process. To solve this problem, in this paper we propose a method to reduce computational cost of the improved super-resolution method by considering the statistics of motion vectors obtained by DME using OBM. This method can reduce the entire computational cost up to 29.9 ∼ 49.1% depending on a given video sequence while completely maintaining the original performance of the improved super-resolution method using OBM. Also, we try to further reduce computational cost by relaxing the complete original performance preservation requirement. With this additional attempt, we can further reduce computational cost up to 16.9 ∼ 20.8% without serious deterioration of the quality of reconstructed images.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128612358","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}

Based on the position of secondary stroke, Uyghur characters can be separating into 4 groups. In this case, the unknown input character compares to other characters in its corresponding group only. This will be shortening the comparison time. The experiment result of freely-written 10 dataset showed that, the comparison time is reduced by 64.32% while the recognition rate improved 5.87%. The Approximate Stroke Sequence String Matching method is applied to Uyghur handwriting character recognition and an average recognition rate of 93.95% is obtained. It is improved to 96.6% while using the structure information of handwritten characters. Based on these results we discuss that, the recognition rate will be improved by the using of some other features like character frequency, the number of secondary strokes, and other.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121266865","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}
