Abstract: The ID card recognition based on the mobile platform has a wide application. This paper studies the character segmentation method for ID card image which is taken by an intelligent mobile phone. The character segmentation method based on image contrast is proposed, which can adaptively adjust the slope of an ID card image and can effectively realize accurate character segmentation, and is also beneficial to ID character recognition on mobile platform.

Key words: ID character recognition, slope correction, character segmentation
