hue_saturation_value

HueSaturationValue

Bases: ImageOnlyAlbumentation

Randomly modify the hue, saturation, and value of 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
hue_shift_limit Union[int, Tuple[int, int]]

Range for changing hue. If hue_shift_limit is a single int, the range will be (-hue_shift_limit, hue_shift_limit).

20
sat_shift_limit Union[int, Tuple[int, int]]

Range for changing saturation. If sat_shift_limit is a single int, the range will be (-sat_shift_limit, sat_shift_limit).

30
val_shift_limit Union[int, Tuple[int, int]]

range for changing value. If val_shift_limit is a single int, the range will be (-val_shift_limit, val_shift_limit).

20
Image types

uint8, float32
