A preprocessing layer which randomly varies image width during training.
This layer will randomly adjusts the width of a batch of images 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. 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. By default, this layer is
inactive during inference. For an overview and full list of preprocessing
layers, see the preprocessing [guide]
(https://www.tensorflow.org/guide/keras/preprocessing_layers).
Arguments:
factor:
A positive float (fraction of original width), 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 width changed by a random amount in the range [20%, 30%].
factor=(-0.2, 0.3) results in an output with width changed by a random
amount in the range [-20%, +30%]. factor=0.2 results in an output
with width changed by a random amount in the range [-20%, +20%].
interpolation:
String, the interpolation method.
Defaults to bilinear.
Supports "bilinear", "nearest".
The tf methods "bicubic", "area", "lanczos3", "lanczos5",
"gaussian", "mitchellcubic" are unimplemented in tfjs.
seed:
Integer. Used to create a random seed.
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, random_width, channels).
