Abstract
Image archive is a transformation from source toits digital form. This process, however, often leads to theirregular distribution of image illumination, which distortingthe content of images. In this article, we propose a hybridillumination technique based on double Niblack thresholds torefine the brightness of under-exposure and over-exposureimages, including the text image and the text-photo image.Experimental results have shown that the new method caneffectively adjust the illumination to improve the quality ofdigital images.
