tf.keras.layers.RandomCrop  |  TensorFlow v2.16.1 (original) (raw)

A preprocessing layer which randomly crops images during training.

Inherits From: Layer, Operation

tf.keras.layers.RandomCrop(
    height, width, seed=None, data_format=None, name=None, **kwargs
)

During training, this layer will randomly choose a location to crop images down to a target size. The layer will crop all the images in the same batch to the same cropping location.

At inference time, and during training if an input image is smaller than the target size, the input will be resized and cropped so as to return the largest possible window in the image that matches the target aspect ratio. If you need to apply random cropping at inference time, set training to True when calling the layer.

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.

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 (..., target_height, target_width, channels).
Args
height Integer, the height of the output shape.
width Integer, the width of the output shape.
seed Integer. Used to create a random seed.
**kwargs Base layer keyword arguments, such asname and dtype.
Attributes
input Retrieves the input tensor(s) of a symbolic operation.Only returns the tensor(s) corresponding to the _first time_the operation was called.
output Retrieves the output tensor(s) of a layer.Only returns the tensor(s) corresponding to the _first time_the operation was called.

Methods

from_config

View source

@classmethod from_config( config )

Creates a layer from its config.

This method is the reverse of get_config, capable of instantiating the same layer from the config dictionary. It does not handle layer connectivity (handled by Network), nor weights (handled by set_weights).

Args
config A Python dictionary, typically the output of get_config.
Returns
A layer instance.
