SIFT method for paper detection system
Juan Zhu, Shuai Wang, Fanying Meng · 2011
Traditional detect method could not deal well with the problem of paper zooming. This paper introduces scale invariant feature transform to the paper detection system. The hardware of paper detection system consists of digital signal processor and complex programmable logic device. The hardware can accomplish image acquisition and processing. The software of this system use SIFT method to detect the papers. Compared to the traditional method, this algorithm deals better with detection process.
