random_fog

RandomFog

Bases: ImageOnlyAlbumentation

Add fog to an image.

Parameters:

Name Type Description Default
inputs Union[str, Iterable[str]]

Key(s) of images to be modified.

required
outputs Union[str, Iterable[str]]

Key(s) into which to write the modified images.

required
mode Union[None, str, Iterable[str]]

What mode(s) to execute this Op in. For example, "train", "eval", "test", or "infer". To execute regardless of mode, pass None. To execute in all modes except for a particular one, you can pass an argument like "!infer" or "!train".

None
ds_id Union[None, str, Iterable[str]]

What dataset id(s) to execute this Op in. To execute regardless of ds_id, pass None. To execute in all ds_ids except for a particular one, you can pass an argument like "!ds1".

None
fog_coef_lower float

Lower limit for fog intensity coefficient. Should be in the range [0, 1].

0.3
fog_coef_upper float

Upper limit for fog intensity coefficient. Should be in the range [0, 1].

1.0
alpha_coef float

Transparency of the fog circles. Should be in the range [0, 1].

0.08
Image types

uint8, float32
