AdjustContrast

public final class AdjustContrast

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`.

Constants

String

OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "AdjustContrastv2"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the 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.

public static AdjustContrast<T> create (Scope scope, Operand<T> images, Operand<TFloat32> 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

public Output<T> output ()

The contrast-adjusted image or images.
