Non-uniform Illumination Document Image Binarization Using K-Means Clustering Algorithm
2021 IEEE 9th International Conference on Information, Communication and Networks (ICICN)(2021)
摘要
Good binarization result is of great help to the afterwords document image analysis and optical character recognition(OCR). However, non-uniform illumination document image binarization is a very challenging task due to high variation between the document background and foreground. This paper describes a new K-Means clustering based algorithm for non-uniform illumination document image binarizatio...
