比较与tf.image.rgb_to_grayscale的功能差异
tf.image.rgb_to_grayscale
tf.image.rgb_to_grayscale(
images,
name=None
)
更多内容详见tf.image.rgb_to_grayscale。
mindspore.dataset.vision.ConvertColor
class mindspore.dataset.vision.ConvertColor(
convert_mode
)
使用方式
TensorFlow:将图像从RGB图转换为灰度图。
MindSpore:转换图像的色彩空间,其中包括将RGB图转换为灰度图。
代码示例
# 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, 3)).astype(np.float32)
result = ds.vision.ConvertColor(ConvertMode.COLOR_RGB2GRAY)(image)
print(result.shape)
# (28, 28)
# The following implements rgb_to_grayscale with TensorFlow.
import tensorflow as tf
image = tf.random.normal((28, 28, 3))
result = tf.image.rgb_to_grayscale(image)
print(result.shape)
# (28, 28, 1)
