Exposure Bracketing Techniques for Camera Document Image Enhancement

Exposure Bracketing Techniques for Camera Document Image Enhancement

Capturing document images using digital cameras in uneven lighting conditions is challenging, leading to poorly captured images, which hinders the processing that follows, such as Optical Character Recognition (OCR). In this paper, we propose the use of exposure bracketing techniques to solve this p...
