tf.random_crop是tensorflow中的随机裁剪函数，可以用来裁剪图片。我采用如下图片进行随机裁剪，裁剪大小为原图的一半。



如下是实验代码

import tensorflow as tf
import matplotlib.image as img
import matplotlib.pyplot as plt
sess = tf.InteractiveSession()
image = img.imread('D:/Documents/Pictures/logo3.jpg')

reshaped_image = tf.cast(image,tf.float32)
size = tf.cast(tf.shape(reshaped_image).eval(),tf.int32)
height = sess.run(size[0]//2)
width = sess.run(size[1]//2)
distorted_image = tf.random_crop(reshaped_image,[height,width,3])
print(tf.shape(reshaped_image).eval())
print(tf.shape(distorted_image).eval())

fig = plt.figure()
fig1 = plt.figure()
ax = fig.add_subplot(111)
ax1 = fig1.add_subplot(111)
ax.imshow(sess.run(tf.cast(reshaped_image,tf.uint8)))
ax1.imshow(sess.run(tf.cast(distorted_image,tf.uint8)))
plt.show()

如下是随机实验两次的结果
