用Python进行简单的图片数字识别（1）

一、源代码

from PIL import  Image
im = Image.open("F:/result/4.jpg")
#  先将图片转为固定宽高如55*55以符合一行txt文件
im = im.resize((55,55))
fh = open("F:/result/7.txt", "a")
width = im.size[0]
height = im.size[1]
#  k = im.getpixel((1,9))  获取RBG颜色对照数：RBG(255,255,255)白色；RBG（0,0,0）黑色
for i in range(0,width):
    for j in range(0,height):
        cl = im.getpixel((i,j))
        clall = cl[0]+cl[1]+cl[2]
        if(clall==0):
            #黑色
            fh.write("1")
        else:
            #不是黑色
            fh.write("0")
    fh.write("\n")
fh.close()

二、原图片

 

三、识别后的txt文件
