A preprocessing layer that randomly applies shear transformations
Description
images.
This layer shears the input images along the x-axis and/or y-axis by a
randomly selected factor within the specified range. The shear
transformation is applied to each image independently in a batch. Empty
regions created during the transformation are filled according to the
fill_mode and fill_value parameters.
Usage
layer_random_shear(
object,
x_factor = 0,
y_factor = 0,
interpolation = "bilinear",
fill_mode = "reflect",
fill_value = 0,
data_format = NULL,
seed = NULL,
...
)
Arguments
object
Object to compose the layer with. A tensor, array, or sequential model.
x_factor
A tuple of two floats. For each augmented image, a value
is sampled from the provided range. If a float is passed, the
range is interpreted as (0, x_factor). Values represent a
percentage of the image to shear over. For example, 0.3 shears
pixels up to 30% of the way across the image. All provided values
should be positive.
y_factor
A tuple of two floats. For each augmented image, a value
is sampled from the provided range. If a float is passed, the
range is interpreted as (0, y_factor). Values represent a
percentage of the image to shear over. For example, 0.3 shears
pixels up to 30% of the way across the image. All provided values
should be positive.
interpolation
Interpolation mode. Supported values: "nearest",
"bilinear".
fill_mode
Points outside the boundaries of the input are filled
according to the given mode. Available methods are "constant",
"nearest", "wrap" and "reflect". Defaults to "constant".
-
"reflect": (d c b a | a b c d | d c b a)
The input is extended by reflecting about the edge of the
last pixel.
-
"constant": (k k k k | a b c d | k k k k)
The input is extended by filling all values beyond the edge
with the same constant value k specified by fill_value.
-
"wrap": (a b c d | a b c d | a b c d)
The input is extended by wrapping around to the opposite edge.
-
"nearest": (a a a a | a b c d | d d d d)
The input is extended by the nearest pixel.
Note that when using torch backend, "reflect" is redirected to
"mirror" (c d c b | a b c d | c b a b) because torch does
not support "reflect".
Note that torch backend does not support "wrap".
fill_value
A float representing the value to be filled outside the
boundaries when fill_mode="constant".
data_format
String, one of "channels_last" (default) or
"channels_first". The ordering of the dimensions in the inputs.
"channels_last" corresponds to inputs with shape
(batch, height, width, channels) while "channels_first"
corresponds to inputs with shape
(batch, channels, height, width).
seed
Integer. Used to create a random seed.
...
For forward/backward compatability.
