随机翻转层
RandomFlip class
tf_keras.layers.RandomFlip(mode="horizontal_and_vertical", seed=None, **kwargs)
A preprocessing layer which randomly flips images during training.
This layer will flip the images horizontally and or vertically based on the
mode attribute. During inference time, the output will be identical to
input. Call the layer with training=True to flip the input.
Input pixel values can be of any range (e.g. [0., 1.) or [0, 255]) and
of integer or floating point dtype.
By default, the layer will output floats.
For an overview and full list of preprocessing layers, see the preprocessing guide.
Input shape
3D (unbatched) or 4D (batched) tensor with shape:
(..., height, width, channels), in "channels_last" format.
Output shape
3D (unbatched) or 4D (batched) tensor with shape:
(..., height, width, channels), in "channels_last" format.
Arguments
- mode: String indicating which flip mode to use. Can be
"horizontal","vertical", or"horizontal_and_vertical"."horizontal"is a left-right flip and"vertical"is a top-bottom flip. Defaults to"horizontal_and_vertical" - seed: Integer. Used to create a random seed.
