您好!
scale是通过相机meta data中的白电平white_level和黑电平black_level,即scale=white_level-black_level。这一部分主要负责相机量化噪声的合成部分,在我们以及ELD的噪声模型中,量化噪声被建模为 $U(-\frac{1}{2q}, \frac{1}{2q})$,其中 $q$ 为量化步长,即 scale。
white_level
black_level
scale=white_level-black_level
scale
如果您想合成低光图像,您只需修改ratio为您需要的范围。由于LED主要面向的任务是极暗场景的去噪任务,因此ratio范围较大,在合成的图像“很黑”,可能不符合您的预期,您可以适当的降低ratio范围。
ratio
btw, 如果LED对您的项目有帮助的话,希望您可以帮我们点个star🌟,这将是对我们进一步科研的莫大鼓励!感谢!
Sorry, something went wrong.
