There are many methods for sign language recognition, some of which are based on Hidden Markov Model (HMM) and others are based on Support Vector Machine (SVM) and so forth. In fact, the most of previous methods recognize fingerspelling using video sequence because some fingerspellings are accompanied by movement. Some methods use Microsoft Kinect or Leap Motion controller to obtain the finger movement. Some fingerspellings, however, are not accompanied by movement and can be recognized with just one snap shot of fingerspelling. Therefore, this paper proposes a recognition method of fingerspelling without movement. The target fingerspellings are 41 characters without movement in Japanese sign language, and the method uses only one picture. Some of fingerspellings are easily recognized and others are not so that the method is based on pattern recognition using classification tree and machine learning with SVM for easily recognized fingerspellings and difficultly recognized ones, respectively. As the result of the experiment, the averaged recognition rate was 86%.","PeriodicalId":333647,"journal":{"name":"2017 Nicograph International (NicoInt)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893335","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}

While expert counselors are instructing the counseling skill to beginner counselors, we consider that the reaction of a client for a beginner counselor's question is important to visualize in an appropriate method. To respond the request, we have developed a system for visualizing the flow of conversation in counseling. However, the expert counselor as the system user requires to correct the initial classification result manually, and the work burden is large, because the accuracy of the category classification of conversation data is very low in the current system. To improve this problem, we have implemented on the category classification method of text data with SVM (Support Vector Machine) as machine learning technique to visualize the flow of conversation in counseling. In addition, we have compared and evaluated with results of the initial classification method of the current system. As these results, we have shown that the accuracy rate of the classification method with SVM become higher than the results in the current system.","PeriodicalId":333647,"journal":{"name":"2017 Nicograph International (NicoInt)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128023013","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 studies how to catch the shape and intensity deformation characteristics of this type of severe weather system, which includes the wind field estimation and typhoon structure prediction in a short period of time. A correlation matching approach is used to retrieve typhoon wind field without the estimation of typhoon center. Firstly, an energy function is designed to dynamically restrain the tracking area instead of using a constant one. Then for each grid at previous time step, a corresponding one with maximum correlation coefficient at current time step is computed. The collection of these computed grid pairs reflects the movement of circulation structure and thus the wind field is obtained. Finally, a quality control is performed with total variation reconstruction to smooth the global wind field by eliminating local error data and filling missing data points with the average velocity in the neighborhood. With the computed wind field, the short-term forecasting of typhoon structure that represented by radar echo data is realized by the semi-Lagrangian advection approach. Experimental result shows that the proposed method could retrieve accurate and smooth typhoon wind field compared with observation data, or data computed with optical flow algorithm, and could predict relative accurate typhoon structure in 1 hour.","PeriodicalId":333647,"journal":{"name":"2017 Nicograph International (NicoInt)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125267173","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}
