"""Randomly modify the hue, saturation, and value of an image.
Args:
inputs: Key(s) of images to be modified.
outputs: Key(s) into which to write the modified images.
mode: 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".
ds_id: 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".
hue_shift_limit: Range for changing hue. If hue_shift_limit is a single int, the range will be
(-hue_shift_limit, hue_shift_limit).
sat_shift_limit: Range for changing saturation. If sat_shift_limit is a single int, the range will be
(-sat_shift_limit, sat_shift_limit).
val_shift_limit: range for changing value. If val_shift_limit is a single int, the range will be
(-val_shift_limit, val_shift_limit).
