This method utilizes the contour tracing and corner detection technique for identification of key corner points, and then locates the potential code region by the finder pattern. The timing patterns are used to confirm a real code region. Moreover, image pre-processing procedures are merged in order to reduce the time and memory consumption. We test our method on images taken by embedded camera device under different environment, such as normal illumination, highlight spot and inadequate illumination. The results show that the method is fast for multi-QR-code extraction and practical for a digital camera with embedded DSP capable of performing advanced image processing algorithms on the fly.","PeriodicalId":328792,"journal":{"name":"2011 IEEE International Conference on Anti-Counterfeiting, Security and Identification","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127370198","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 presents an efficient and accurate methodology which links the on-chip and off-chip designs together. To validate this methodology, a 12bits 500MHz current-steering, nyquist rate DA converter is designed.

Apart from the various GPS tracking devices this paper introduces a first of its kind vehicle tracking system that works only using GSM technology, which would be the cheapest source of vehicle tracking anti-theft system. It is a small kit that consists of a GSM module and several other components. The system can be switched ON by an SMS from the owner, which in turn instructs the microcontroller to turn OFF the vehicle, receive information about the vehicle's current location or more. Once this is done, the microcontroller stimulates the GSM module to forward the details of the nearest Base Station to the owner's mobile via text message. The microcontroller which receives the delivery messages through the GSM module evaluates the time gap between successive messages to determine the exact location of the vehicle in a given area. The enviable advantage of this system is that it helps the owner in tracking the vehicle at a greater pace, and reduces the complexities comparing other system, besides being a cheapest alternative for anti-theft system as well.","PeriodicalId":328792,"journal":{"name":"2011 IEEE International Conference on Anti-Counterfeiting, Security and Identification","volume":"562 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116904086","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}
