tensorflow::ops::DrawBoundingBoxes

#include <image_ops.h>

Draw bounding boxes on a batch of images.

Summary

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 and the bounding box is [0.1, 0.2, 0.5, 0.9], the bottom-left and upper-right coordinates of the bounding box will be (10, 40) to (50, 180).

Parts of the bounding box may fall outside the image.

Arguments:

  • scope: A Scope object
  • 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.

Returns:

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