In Asian countries, seals are widely used for authenticating the identity of a person or an organization. Therefore, the ability to efficiently verify whether a seal is either genuine or forged is important. Both rectangular and circular seal imprints are considered in this work. Geometric transformation is performed to align the perspective of the detected imprint image with the reference imprint. After the edge-differences between the reference image and the detected image are computed, a dist...

In Asian countries, seals are widely used for authenticating the identity of a person or organization. Therefore, the ability to efficiently verify whether a seal is either genuine or forged is important. We propose an effective method of verification based on Hough transformation to approximate the imprint borders and the four vertexes, and use geometric transformation to align the perspective of the detected imprint image with the genuine imprint. After the edge-difference images between the o...
