        参考资料：《Python图像处理实战》
        安装方法：pip install scikit-image
        导入方法：

from skimage.io import imread, imsave, imshow, show, imread_collection, imshow_collection
from skimage import color, viewer, exposure, img_as_float, data
from skimage.transform import SimilarityTransform, warp, swirl
from skimage.util import invert, random_noise, montage

使用scikit-image内置的数据集

im = data.astronaut()
imshow(im), show()

Read and display multiple images simultaneously at once：

imread_collection? =>
Signature:
imread_collection(

    conserve_memory=True,
    plugin=None,
    **plugin_args,
)
Docstring:

Type:      function

使用方法：

ic = imread_collection(ic = imread_collection(['images/69015.jpg','images/210088.jpg', 'images/cat1.png'])

# <Figure size 640x480 with 4 Axes>
