PIL
1 from PIL import Image 2 import matplotlib.pyplot as plt 3 import numpy as np 4 %matplotlib inline 5 6 image = Image.open('1.png') 7 plt.imshow(image) 8 print(image.size)
输出的是(宽,高)
读取的格式需要将image转换成np.array才可以:
image_array = np.array(image) print(image.shape) >>输出的是 (高,宽,通道数)
tensorflow
1 import tensorflow as tf 2 import numpy as np 3 import matplotlib.pyplot as plt 4 image_contents = tf.read_file('1.png') #读取文件 5 image = tf.image.decode_png(image_contents, channels=3) #解码jpeg 6 with tf.Session() as sess: 7 sess.run(tf.global_variables_initializer()) 8 img=sess.run((image)) #img为三维数组 9 print (img.shape) #输出数组形状 10 print (img) #打印数组 11 plt.imshow(img) #显示数组 12 plt.show()
输出的是(高,宽,channel)
