python PIL模块使用案例

整体思路：
求解的所有文件固定位置灰度值平均值，并作图

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

import matplotlib.animation as ani
os.chdir('D:\python\work\工作平台\diff-gate time')  

#建立所有文件名称的list，使用循环异常打开
all_filename=os.listdir()
print(all_filename)

def sov_ever(filename):
    imgData = np.fromfile(filename, dtype='uint16')
    img=imgData.reshape(3072, 3072, 1)
    img_select=[]
    a=1844
    b=576
    for i in range(0,900):
        for j in range(0,900):
            img_select.append(img[a+i][b+j])
    LSB=np.mean(img_select)
    return LSB

all_LSB=[]
for i in all_filename:
    all_LSB.append(sov_ever(i))
