Auto-Recognition of the Book Call Number Based on Image Processing

The book call number is a series of codes which are given to each kind of books by the library. It is used to locate the position of each book on the shelf. So, how to recognize the book call number automatically has great practical significance for determining the correct position of books automatically. This paper introduces an automatic recognition algorithm for the book call number images. The algorithm includes several steps: image preprocessing, call number locating, image binarization, character segmentation and character recognition. The details of each step are discussed. The experiment results proved that this algorithm can recognize the book call number automatically.
