The vertex and fragment shader programs in embedded GPU are programmed with embedded system shading language(ESSL). The shader compiler for ESSL should be designed considering several distinct features of ESSL and GPU. In this paper, we present ESSL compiler techniques for embedded GPU. The compiler can optimize the code and data memory size as well as improve the performance of shader code by fully exploiting the special architecture of target GPU. Experiments show that the proposed optimization techniques can reduce the code size by up to 10.3% and the execution cycles by up to 16.8%.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122512215","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}

For this purpose, we propose a new concept of vision key for retrieving consumer product images. In our system, rather than considering an image as a whole, we consider it as a set of regions or sub-images with completely different semantic meanings. By using the properties of equivalence classes in the Markov chain, we first perform image segmentation and initial pixel grouping process. We then establish vision keys by using a Markov stationary feature. Finally, in the retrieval phase, users can interactively search candidate images which contain vision keys. In order to confirm the efficiency of our proposed method, we present the experimental results achieving on higher accuracy rates.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134230696","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 reconstruct the boundary positions, conventional methods offer an array consists of a large number of elements (e.g. microphones and loudspeakers). This research aims to estimate the correct boundary position using a small number of microphones, by developing a signal processing method which utilizes the direction of arrival(DOA) of direct and reflected sounds. The performance of the proposed method is evaluated in numerical simulation in which the human voice is assumed to be a sound source. From the obtained results, we found that the estimation result involves some errors due to approximations in the proposed algorithm. However, we also found that employment of the correction function is effective to minimize the estimation error. As a result, the proposed method may achieve compassing the spatial shape using a small number of microphones with actual calculation cost.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115215621","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}
