Abstract

During the image archive transformation, artificial operations often lead to the irregular light distribution, which distorting the content. In this article, we propose a new light-balance technique for refining the under-exposure images, including the text and the text-photo ones. In addition, we have introduced the ownership concept to the transformation procedure so that a restorer can demonstrate who has done this work in the future. Specifically, embedding ownership information into the carrier and refining the light simultaneously can efficiently preserve the image quality. Experimental results have shown that the new method can effectively compensate the brightness to improve the quality of digital images. Furthermore, the embedded logo is able to firmly resist the JPEG compression operation; thus, the outcome is suitable for the Internet delivery.
