Logo detection and replacement method based on SIFT algorithm

Abstract

Logo recognition technology can be used to identify the authenticity of logos, and logo substitution technology can be used to add watermarks to images, print anti-counterfeiting, effect generation, image composition, and even document signing. It can facilitate specific people and protect the rights of the author. This paper is a study of Logo recognition and substitution based on the SIFT algorithm, using the SIFT description to recognize the presence or absence of a pre-stored Logo in the Logo Library. The logo is replaced by a logo from the logo library.
