DE has been widely applied to solve various optimization problems. Additionally, many modified DE algorithms have been developed in an attempt to improve search performance. In this paper, we propose island-based DE with varying subpopulation size. Island model is one of the effective parallel distributed model in evolutionary algorithms. In the proposed method, total population is divided into independent sub-populations called islands. The basic island model uses same control parameters for each subpopulation. In contrast, we allocate different control parameters to each island. Therefore, each island has a different convergence characteristic by using own control parameters. At fixed generation intervals, migration among islands is performed in order to preserve diversity of subpopulation. Additionally, by incorporating the operation of individual transfer, proposed method can vary subpopulation dynamically according to the function landscape. Numerical experiments are performed to illustrate the performance of the proposed method compared with basic DE. The results show that the proposed method outperforms basic DE on standard test functions including various landscape features.","PeriodicalId":257474,"journal":{"name":"2013 IEEE 6th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125494647","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}

To give an RA diagnosis, a hand radiograph is taken and analyzed. Hand bone radiograph analysis starts with the detection of the boundary of bones. It is, however, an extremely exhausting and time consuming task for radiologists, not only because of the complexity, but also because of the precision required for a correct diagnosis. Automatic bone boundary detection is thus required. The Level Set Method has been widely used in boundary detection. However, the convergence and stability of the level set are strongly affected by the speed function and the parameters of the level set, which often leads to either a complete breakdown or a premature termination of the curve evolution process, resulting in unsatisfactory results. In this paper, we propose a modified speed function of the level set for bone boundary detection in hand radiographs. And in order to preserve the boundary of an image and to reduce noise, we further apply diffusion filter to substitute Gaussian Filter in the standard Level Set Method. Evaluating the experiments using a particular set of hand bones radiographs, the proposed method worked well for almost all of the images that we used.","PeriodicalId":257474,"journal":{"name":"2013 IEEE 6th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125904166","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 complete our purpose, the evaluation criteria for saddle setting by using bio-signals of a cyclist who pedals a bicycle have to be established firstly. We focus on patterns of muscle activity of the leg muscles that activate in pedaling exercise, and assume that undesirable pattern of muscle activity would appear in the pedaling motion of inexperienced cyclists. We use principal component analysis (PCA) to extract the features of muscle activity from the leg muscles. Our previous work has already clarified that the PCA scores come close to zero in the pedaling motion performed by a skilled cyclist at the saddle height which is subjectively evaluated good. In this paper, we add other degrees of freedoms of saddle setting such as fore-and-back position and angle adjustment to the experimental device. Surface electromyogram (SEMG) of the leg muscles has also been used to measure bio-signals of a cyclist during pedaling exercise. With the use of the aforementioned experimental environment, the effects of setting height and fore-and-back position to the pattern of muscle activity of the leg muscles are investigated in this paper.","PeriodicalId":257474,"journal":{"name":"2013 IEEE 6th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114190965","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}

Our method is to learn relationship of pixel values between high-resolution (HR) image and low-resolution (LR) image using CGP, and we construct a SR rule of generating SR image from a LR input image. A single pixel and its neighbor pixels of the LR input image are set to the inputs of CGP. And then, pixel values of the SR image are obtained from the calculated outputs of CGP. Therefore, the SR image is generated from the LR input image. In addition, multiple CGP can improve the quality of SR image. Because our method is to perform for each pixel independently, our method is suitable to parallel processing. Therefore, in order to reduce computational cost, we use parallel processing with graphics processing unit (GPU). Experimental results show efficient processing is constructed. Our method is little less quality than one conventional work which is the state of the art method on image quality, however to perform overwhelmingly faster than the conventional work. We can construct fast and accurate single-frame super-resolution.","PeriodicalId":257474,"journal":{"name":"2013 IEEE 6th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116532661","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}
