Converts one or more images from Grayscale to RGB.

Outputs a tensor of the same DType and rank as images. The size of the last dimension of the output is 3, containing the RGB value of the pixels. The input images' last dimension must be size 1.

original = tf.constant([[[1.0], [2.0], [3.0]]])
converted = tf.image.grayscale_to_rgb(original)
[[[1. 1. 1.]
  [2. 2. 2.]
  [3. 3. 3.]]]

images The Grayscale tensor to convert. The last dimension must be size 1.
name A name for the operation (optional).
