Extraction and Segmentation of Books Call Number Image for Books on the Shelves of Library

摘要

It is a key technology that extract and segment book call number from books’ backbone images for book retrieval and return robot to take an operation of sending and withdrawing books to or from the shelves of library. This paper presents an image extraction and segmentation method using color feature and edge information to segment adjacent book call number with similar background. Take thick, thicker, medium thick, thin, little thin and hybrid books’ backbone images as experiment samples, and the results show that this method effectively extracts and segments adjacent book call number. The segmentation approach provides a technical support for book retrieval and return robot to carry out automatic books’ retrieval and return operation.
