Thanks
Thank you <a target = "_blank" href="https://www.csie.ntu.edu.tw/~cyy/publications/papers/Lin2020BAD.pdf">Yun-Hsuan Lin</a>, and <a target = "_blank" href="https://ieeexplore.ieee.org/abstract/document/9053378">Jian-Ren Wang</a> for citing my work! <br><br> In 2016 ACCV, Bako, and I talked that this field only gets a few public attention. Now I am glad that many people are showing interest on this (and on Bako's) work. <br><br>
About me
I am not currently working on this field... :D

Tips
(2020/04/22) For those who are interested in applying this method in printed colored documents (i.e., magazine), <a target = "_blank" href="https://github.com/seungjun45/Water-Filling/issues/2">"alexliyang"</a> suggests that spliting image channels would help improving performance. (Thank you!) <br> <br> If you think the results are too bright, you can adjust brightness factor from 0.85 to lower! :)
