In the field of astronomy, some physical models have been developed to simulate the sun’s turbulence. Most of the previous models are difficult to be applied in the making of CG images since they require a considerable amount of time even when using a supercomputer. The subject of our research is the visual simulation of the phenomena observed above the photosphere, namely solar prominences, because these are characteristic phenomena of the sun that can greatly influence the visual impact in movies and games.The sun is mainly composed of ionized plasma, and its behavior can be treated as a fluid. However, unlike gas, the plasma fluid is influenced by the magnetic field. Thus, magnetic field calculations are needed to calculate the plasma behavior. We use the magnetohydrodynamics (MHD) equations to simulate the behavior of plasma. We propose a new method which can simulate a prominence in a practical computation time. The computation cost is reduced by simplifying the phenomena inside the sun: we only consider the phenomena after the solar prominence erupts because the phenomena before the eruption dose not manifest itself in a visual way. To render the simulation results, we emulate an observation method that extracts the specific spectrum emission from the solar plasma.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124650809","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}

As it is very time consuming to generate digital road maps this way, we propose a system to generate digital maps using image processing of aerial images. Conventionally, most methods of road extraction use RGB features. However, the use in urban areas of RGB features has many problems as they are affected severely by shadows cast by buildings. On the other hand, road extraction using a Digital Surface Model (DSM) is not affected by shadows because a DSM is elevation data. However, it is too difficult to distinguish between a road and other objects, such as a railway, because the elevations of these objects are similar. In this paper, we use DSM and RGB aerial images to resolve the problems of each type of data. We segment a DSM to extract the road areas from the DSM; however, the segmentation method conventionally used could not extract narrow roads because that method is sensitive to noise in a DSM. In light of this, we next propose a method of image segmentation using Boundary code. The proposed segmentation method is robust against the noise in a DSM. In an experiment using actual data, the accuracy of road extraction using the proposed method was 83.7%, against the 76.0% achieved using the conventional method. In addition, the proposed method achieves faster segmentation than the conventional method. Moreover, this method extracted road areas more accurately in urban areas than by just using RGB or DSM.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130749502","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}
