org.tensorflow.op.image

Class DrawBoundingBoxes<T extends TNumber>

java.lang.Object

org.tensorflow.op.RawOp

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

Type Parameters:

T - data type for output output

All Implemented Interfaces:

org.tensorflow.ndarray.Shaped, Op, Operand<T>

@Operator(group="image")
public final class DrawBoundingBoxes<T extends TNumber>
extends RawOp
implements Operand<T>

Draw bounding boxes on a batch of images. Outputs a copy of images but draws on top of the pixels zero or more bounding boxes specified by the locations in boxes. The coordinates of the each bounding box in boxes are encoded as [y_min, x_min, y_max, x_max]. The bounding box coordinates are floats in [0.0, 1.0] relative to the width and height of the underlying image.

For example, if an image is 100 x 200 pixels (height x width) and the bounding box is [0.1, 0.2, 0.5, 0.9], the upper-left and bottom-right coordinates of the bounding box will be (40, 10) to (100, 50) (in (x,y) coordinates).

Parts of the bounding box may fall outside the image.

Factory method to create a class wrapping a new DrawBoundingBoxesV2 operation.

Type Parameters:

T - data type for DrawBoundingBoxesV2 output and operands

Parameters:

scope - current scope

images - 4-D with shape [batch, height, width, depth]. A batch of images.

boxes - 3-D with shape [batch, num_bounding_boxes, 4] containing bounding boxes.

colors - 2-D. A list of RGBA colors to cycle through for the boxes.

Returns:

a new instance of DrawBoundingBoxes

output

public Output<T> output()

Gets output. 4-D with the same shape as images. The batch of input images with bounding boxes drawn on the images.

Returns:

output.

asOutput

public Output<T> asOutput()

Description copied from interface: Operand

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.

Specified by:

asOutput in interface Operand<T extends TNumber>
