Adjust the hue of RGB images by a random factor.
該函數用於隨機調整RGB圖像的色調。

tf.image.random_hue(
    image, max_delta, seed=None
)

Equivalent to adjust_hue() but uses a delta randomly picked in the interval [-max_delta, max_delta].
max_delta must be in the interval [0, 0.5].

在區間[-max_delta, max_delta]上隨機選擇delta值，更改圖片色調。
max_delta必須在區間[0, 0.5]中。

Args:

• image: RGB image or images. Size of the last dimension must be 3.

• image: 單張RGB圖片或多張RGB圖片，最後一維必須爲3

• max_delta: float. Maximum value for the random delta.

• max_delta: 浮點數，指定隨機 delta 值的最大值

• seed: An operation-specific seed.
  It will be used in conjunction with the graph-level seed to determine the real seeds that will be used in this operation.
  Please see the documentation of set_random_seed for its interaction with the graph-level random seed.

• seed: 特定操作的種子。(注：筆者不太明白這個種子和隨機數種子有什麼區別，只是感覺有點兒玄乎)

Returns:

• Adjusted image(s), same shape and DType as image.
• 色調調整過後的圖片，與輸入 image 有相同的shape和類型

Raises:

• ValueError: if max_delta is invalid.
• 如果 max_delta 是無效的，將 raise ValueError，max_delta必須在區間[0, 0.5]中。
