1.1 读入

from PIL import Image
import numpy as np
import matplotlib.pyplot as plt

path1 = "J:/code/cardiac_data/2Dwithoutcenter1/27-18-3.npz"
path2 = "J:/code/cardiac_data/2Dwithoutcenter1/27-7-3.npz"
data1 = np.load(path1)
img_data1 = data1['img']
seg_data1 = data1['seg']
data2 = np.load(path2)
img_data2 = data2['img']
seg_data2 = data2['seg']
# show the details
data1.files

['img', 'seg']

1.2 大小

img.shape

(200, 200)

2. 读取图片

plt.imshow(img_data1)
