org.tensorflow.op.image

Class AdjustContrast<T extends Number>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.image.AdjustContrast<T>

Type Parameters:

T - data type for output() output

All Implemented Interfaces:

Op, Operand<T>

@Operator(group="image")
public final class AdjustContrast<T extends Number>
extends PrimitiveOp
implements Operand<T>

Adjust the contrast of one or more images.

`images` is a tensor of at least 3 dimensions. The last 3 dimensions are interpreted as `[height, width, channels]`. The other dimensions only represent a collection of images, such as `[batch, height, width, channels].`

Contrast is adjusted independently for each channel of each image.

For each channel, the Op first computes the mean of the image pixels in the channel and then adjusts each component of each pixel to `(x - mean) * contrast_factor + mean`.

Method Detail

create

public static <T extends Number> AdjustContrast<T> create(Scope scope,
                                                          Operand<T> images,
                                                          Operand<Float> contrastFactor)

Factory method to create a class wrapping a new AdjustContrast operation.

Parameters:

scope - current scope

images - Images to adjust. At least 3-D.

contrastFactor - A float multiplier for adjusting contrast.

Returns:

a new instance of AdjustContrast

output

public Output<T> output()

The contrast-adjusted image or images.

asOutput

public Output<T> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:

asOutput in interface Operand<T extends Number>
