您好，南开的师兄或老师，您那边可以提供下生成边缘label的python实现么？

我在github里放了matlab的代码，你可以参考下，就三行主要代码，python应该也有对应的实现方法。

好的 谢谢您，我给一下我的实验，给其他同学以参考

import cv2
import numpy as np

# In[2]:

img_path = './ILSVRC2012_test_00000018.png'
img_data = cv2.imread(img_path)
img_data = img_data > 128
print(img_data.shape)

# In[3]:

img_data = np.asarray(img_data[:,:,0], dtype=np.double)
gx,gy = np.gradient(img_data)

# In[4]:

temp_edge = gy*gy + gx*gx

# In[5]:

temp_edge

# In[6]:

temp_edge[temp_edge != 0.0] = 255.0

# In[7]:

temp_edge = np.asarray(temp_edge,dtype=np.uint8)

# In[8]:

cv2.imwrite('./ILSVRC2012_test_00000018_edge_opencv.png',temp_edge)
