python 導入mat文件

 首先導入相關的包

import scipy.io as sio
import os
filepath = os.path.join('../Denoising/Datasets/test/', 'ValidationNoisyBlocksRaw.mat')
print(filepath)
##導入mat文件
img=sio.loadmat(filepath)

導入mat文件返回是一個字典對象。

# print(type(img))
for i in img.keys():
print(i)

 輸出結果

__header__
__version__
__globals__
ValidationNoisyBlocksRaw

aa=img['ValidationNoisyBlocksRaw']
print(type(aa))
print(aa.shape)
b=aa[0,1,:,:]
print(b.shape)
print(type(b))

 輸出
