Differences

TensorFlow: Convert the image from grayscale to RGB.

MindSpore: Convert the color space of the image, including conversion from grayscale to RGB.

Code Example

# The following implements ConvertColor with MindSpore.
import numpy as np
import mindspore.dataset as ds
from mindspore.dataset.vision import ConvertMode

image = np.random.random((28, 28, 1))
result = ds.vision.c_transforms.ConvertColor(ConvertMode.COLOR_GRAY2RGB)(image)
print(result.shape)
# (28, 28, 3)

# The following implements grayscale_to_rgb with TensorFlow.
import tensorflow as tf

image = tf.random.normal((28, 28, 1))
result = tf.image.grayscale_to_rgb(image)
print(result.shape)
# (28, 28, 3)
