[英]Keras ImageDataGenerator brightness range
In the docs for Keras ImageDataGenerator
, there is reference to an arg called brightness_range
(default None
).在 Keras
ImageDataGenerator
的文档中,引用了一个名为brightness_range
的参数(默认为None
)。 The documentation says that this arg accepts文档说这个 arg 接受
Tuple or list of two floats.
元组或两个浮点数的列表。 Range for picking a brightness shift value from.
从中选择亮度偏移值的范围。
That is extremely ambiguous.这是非常模棱两可的。 Does it mean a float within range (0,255)?
这是否意味着范围内的浮点数(0,255)? Or does it mean a float within range (0,1)?
或者它是否意味着范围(0,1)内的浮点数? The lack of specificity suggests that both would work, but I don't know how this tool is meant to be used.
缺乏特异性表明两者都可以工作,但我不知道这个工具是如何使用的。 Is there any further documentation out there or general best practices for using this arg?
是否有任何进一步的文档或使用此 arg 的一般最佳实践?
As this article shows, 0
means no brightness (completely black), 1
means maximum brightness (no change), and anything above just makes the image brighter.如本文所示,
0
表示无亮度(全黑), 1
表示最大亮度(无变化),以上任何内容只会使图像更亮。
