Python怎么读取图片

from PIL import Image
import numpy as np
 
I = Image.open('./cc_1.png') 
I.show() 
I.save('./save.png')
I_array = np.array(I)
print I_array.shape

# matplotlib.image as mpimg 用于读取图片
# 并且读取出来就是array格式
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import numpy as np
I = mpimg.imread('./cc_1.png')
print I.shape
plt.imshow(I)

#cv2.imread()读出来同样是array形式，但是如果是单通道的图，读出来的是三通道的
import cv2
I = cv2.imread('./cc_1.png')
print I.shape

import matplotlib.pyplot as plt
from scipy import misc
import scipy
I = misc.imread('./cc_1.png')
scipy.misc.imsave('./save1.png', I)
plt.imshow(I)
plt.show()

from skimage import io,data
img=data.lena()
io.imshow(img)
