Book cover identification by using four directional features field for a small-scale library system

This paper describes an identification method for book-cover images. It is used in a novel library system using images of books and the borrowers' faces. A returned book is identified from the lent books by processing the images of the book covers. A low-resolution field with four directional features is used to identify the books. These features can be compatible with computation time and performance. To identify a series of books which are similar, but different in just a small area, partial area matching is used. Experiments show the effectiveness of the proposed methods.
