low-light-image-enhancement's Issues

论文复现过程中的一些问题

作者你好,非常感谢你提供的解决方案,最近我在利用opencv复现《Visual Perception Model for Rapid and Adaptive
Low-light Image Enhancement》这篇论文,但是在这过程中碰到了以下几个问题:
(1)Fig.3中的Ic图像是否是HSI色彩空间中的I分量?
(2)Ic是否是归一化浮点表示的格式?
(3)Ib能否直接通过均值滤波得到?我对公式(2)的操作不是很理解。
(4)Hd,Hb这两个图像是否是Ib二值化得到的图像?
(5)对于公式(10),我在实验过程中发现会出现负数。
再次感谢作者的贡献,期待您的恢复,谢谢。
