Linux 下消除马赛克之 Depix

Depix 是用于从像素化屏幕快照中恢复密码的工具。此实现适用于使用线性框滤镜创建的像素化图像。Depix 目前在 GitHub 开源。

实验平台：CentOS Linux release 7.6.1810

Python Version：Python 3.9.0

1.官网

https://github.com/beurtschipper/Depix

2.下载最新包

$ wget https://github.com/beurtschipper/Depix/archive/main.zip

3.解压

$ unzip main.zip
$ cd Depix-main/

4.安装所需依赖

$ pip3 install -r requirements.txt

不安装会有以下报错

Traceback (most recent call last):
  File "/home/jarbo/Depix-main/depix.py", line 1, in <module>
    from depixlib.LoadedImage import *
  File "/home/jarbo/Depix-main/depixlib/LoadedImage.py", line 1, in <module>
    from PIL import Image
ModuleNotFoundError: No module named 'PIL'

5.示例

$ python depix.py -p [pixelated rectangle image] -s [search sequence image] -o output.png
#从屏幕快照中将像素化的块切出为单个矩形。
#在具有相同字体设置（文本大小，字体，颜色，hsl）的编辑器中，将带有预期字符的De Bruijn序列粘贴。
#制作序列的屏幕截图。如果可能，请使用与创建像素化图像相同的屏幕截图工具。

#项目里提供了几个用于测试的文件，目前仅能识别打了马赛克的纯英文或数字。

处理后：

可以大多数都已经被识别出来了。
