Miyanaga","doi":"10.2299/JSP.18.89","DOIUrl":"https://doi.org/10.2299/JSP.18.89","url":null,"abstract":"Dynamic time warping (DTW) is a popular automatic speech recognition (ASR) method based on template matching[1] [2]. DTW algorithm compares the parameters of an unknown word with the parameters of one reference template. But the recognition rate is limited. To increase the number of reference templates for the same word will improve the recognition rate, but it will lead to spend a lot of computing time and memory resource. In this paper we proposed a method to reduce the number of reference templates, thus reduces the computing time and memory resource and also keep the high recognition rate.","PeriodicalId":260263,"journal":{"name":"International Symposium on Signals, Circuits and Systems ISSCS2013","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125531540","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}

The state-of-the-art face recognition algorithms obtain high recognition rates base on demanding costs - computational, energy and memory. The use of these classical algorithms on an embedded system cannot achieve such performances due to the existing constrains: computational power and memory. Our objective is to develop a cheap, real time embedded system able to recognize faces without any compromise on system's accuracy. The system is designed for automotive industry, smart house application and security systems. To achieve superior performance (higher recognition rates) in real time, an optimum combination of new technologies was used for detection and classification of faces. The face detection system uses skeletal-tracking feature of Microsoft Kinect sensor. The face recognition, more precisely - the training of neural network, the most computing-intensive part of the software, is achieved based on the Windows Azures cloud technology.","PeriodicalId":260263,"journal":{"name":"International Symposium on Signals, Circuits and Systems ISSCS2013","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124083446","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 approach is based on a unified VLSI algorithm that uses a parallel restructuring of type IV DCT and DST. It uses parallel pseudo-circular correlation structures as basic computational forms. Most of the unified algorithm can be implemented on the same hardware structure leading to a VLSI chip with a very high percentage of the chip area being used by both the transforms. The unified algorithm can be mapped onto a linear systolic array that have a small number of I/O channels and low I/O bandwidth, which can be efficiently implemented into a VLSI chip.","PeriodicalId":260263,"journal":{"name":"International Symposium on Signals, Circuits and Systems ISSCS2013","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125509301","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}

It is the one that offers the network the “intelligent” character, because it has the capability to collect, process and transmit data to the base station. Because the majority of applications imply the necessity of using a battery as power source, the energy consumption is a priority for prolonging the lifetime of the nodes. This paper proposes and evaluates a new combination of data aggregation techniques. Experimental data were taken after simulating transmission on a software platform, but also from physical wireless sensor nodes.
