首先我们看到这个二维码，判断这应该是点被缩小，所以我们将像黑色素点由1x1向周围放大为9x9，Python脚本如下：```#!/usr/bin/pythonfrom PIL import Image
def rgb2hex(r, g, b):    return int('{:02x}{:02x}{:02x}'.format(r, g, b), 16)
result = ''img = Image.open('brain2.png')
if img.mode in ('RGBA', 'LA') or (img.mode == 'P' and 'transparency' in img.info):       pixels = img.convert('RGBA').load()    width, height = img.size
    for x in range(width):        for y in range(height):            r, g, b, a = pixels[x, y]            if r != 255:                result += '1'                img.putpixel((x+1, y), (0, 0, 0))                img.putpixel((x+1, y-1), (0, 0, 0))                img.putpixel((x+1, y+1), (0, 0, 0))                img.putpixel((x-1, y+1), (0, 0, 0))                img.putpixel((x-1, y-1), (0, 0, 0))                img.putpixel((x-1, y), (0, 0, 0))                img.putpixel((x, y-1), (0, 0, 0))                img.putpixel((x, y+1), (0, 0, 0))    img.show()```然后得到一张图片，扫描二维码得出flag的值。
