Book cover retrieval using enhanced SIFT

Retrieving book covers in web images or in specified database has a wide application prospect, from electronic commerce to picture search. We describe a book cover retrieval system based on enhanced SIFT descriptor by incorporating “binary string” descriptor. Furthermore, a new error recovery based on angle difference of the matching pairs is integrated into the SIFT matching method. Experiments demonstrate that our scheme improves the detection rate and reduces the wrong matching points comparing to the method only using the traditional SIFT descriptor.
