使用方式

TensorFlow:在图像指定位置进行裁剪,入参为裁剪位置的高、宽坐标和裁剪子图的高、宽。

MindSpore:在图像指定位置进行裁剪,入参为裁剪位置的坐标和裁剪子图的大小。

代码示例

# The following implements Crop with MindSpore.
import numpy as np
import mindspore.dataset as ds

image = np.random.random((28, 28, 3))
result = ds.vision.c_transforms.Crop((0, 0), (14, 14))(image)
print(result.shape)
# (14, 14, 3)

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

image = tf.random.normal((28, 28, 3))
result = tf.image.crop_to_bounding_box(image, 0, 0, 14, 14)
print(result.shape)
# (14, 14, 3)
