A preprocessing layer which randomly varies image height during training.
Inherits From: Layer
, Module
tf.keras.layers.RandomHeight(
factor, interpolation='bilinear', seed=None, **kwargs
)
This layer adjusts the height of a batch of images by a random factor.
The input should be a 3D (unbatched) or 4D (batched) tensor in the
"channels_last"
image data format.
By default, this layer is inactive during inference.
For an overview and full list of preprocessing layers, see the preprocessing
guide.
Args |
factor
|
A positive float (fraction of original height), or a tuple of size 2
representing lower and upper bound for resizing vertically. When
represented as a single float, this value is used for both the upper and
lower bound. For instance, factor=(0.2, 0.3) results in an output with
height changed by a random amount in the range [20%, 30%] .
factor=(-0.2, 0.3) results in an output with height changed by a random
amount in the range [-20%, +30%]. factor=0.2results in an output with
height changed by a random amount in the range [-20%, +20%].
