[Python] 웹에서 사진 크롤링하기(Crawling)

1. 필요한 라이브러리 로딩

from skimage.io import imread
from skimage.transform import resize
from matplotlib import pyplot as plt
import matplotlib.cm as cm

 

 

2. 크롤링할 페이지 입력 후 시각화하여 확인

example_file = ("http://upload.wikimedia.org/wikipedia/commons/7/7d/Dog_face.png")
image = imread(example_file)
plt.imshow(image)
plt.show()

 

 

3. 색깔 변환(흑백으로)

image = imread(example_file,as_gray = True)
plt.imshow(image,cmap = cm.gray)

 

 

4. cropping(사진 자르기)

image2 = image[5:70,0:70]
plt.imshow(image2,cmap = cm.gray)
plt.show()

 

 

5. resize

image3 = resize(image2,(30,30),mode='symmetric')
plt.imshow(image3,cmap = cm.gray)
print("data tye: %s, shape : %s" %(type(image3),image3.shape))
