Abstract

Image binarization is an important processing technology. This paper presents a new image binarization method based on dynamic gradient and global threshold. Firstly, a binary image A is generated by using the Otsu's method. Then, a binary image B is gotten with the dynamic gradient method. Lastly, the final binarization image C results from the logic AND operation using A and B. The experimental result shows that the method presented in this paper can preserve details and edges effectively compared with other binarization methods.
