DrawBoundingBoxes

public final class DrawBoundingBoxes

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.

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 DrawBoundingBoxes<T> create (Scope scope, Operand<T> images, Operand<TFloat32> boxes, Operand<TFloat32> colors)

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

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

public Output<T> output ()

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