Working with Depix Tool on Kali Linux OS
Example 1: Depixelize example image created with Notepad and pixelized with Greenshot. Greenshot averages by averaging the gamma-encoded 0-255 values, which is Depix’s default mode.
python3 depix.py -p images/testimages/testimage1.png -s images/searchimages/debruinseq_notepad_Windows10_closeAndSpaced.png
In the below screenshot, we have a pixelized image which we be decoded.
In the below screenshot, we have the possible set of characters that we will be using to get the text from pixelized images.
We have fired up the command to decode the text from the image.
Our result is saved in the .png format file.
We have displayed the output.png file in the below screenshot.
Example 2: Depixelize example image created with Sublime and pixelized with Gimp, where averaging is done in linear sRGB. The backgroundcolor option filters out the background color of the editor.
python3 depix.py -p images/testimages/sublime_screenshot_pixels_gimp.png -s images/searchimages/debruin_sublime_Linux_small.png –backgroundcolor 40,41,35 –averagetype linear
In this example, we will beautify or try to get the text from the image in a more readable format.
Our results are been saved in the output.png file.
We have got the text in a more readable format as compared to in the first example.
Depix – Recovers Passwords From Pixelized Screenshots
Pixelization describes the process of somewhat reducing the resolution of an image to cleanse information. This technique is used to hide sensitive information and it can be communicated between two endpoints. But through various automated tools, we can decode the text and can see the original text in a readable format. Depix tool is an automated cyber security tool that can extract the image and get the readable message or text from the pixelated image. Depix tool is developed in the Python Language and is available on the GitHub platform.
