Least Significant Bit Embedings (LSB) algorithm to extract hidden mesages from 4 tool

I want to be able to use LSB (Least Significant Bits) algorithm to filter images based on the hidden messages.

The objective of this project is to analyse image files from open source tools (listed below) :
1. Steghide : http://steghide.sourceforge.net/index.php
2. OpenStego : https://www.openstego.com/
3. QuickStego : https://quick-stego.software.informer.com/1.2/
4. rStego : https://github.com/akush/rSteg

and develop a UNIVERSAL code that will extract hidden messages from these tools above. The new implementation will be GUI and should extract out the hidden messages from the four tools above

Sample of a demo on steganalysis: https://www.youtube.com/watch?v=k59Sd2k9yMw

Output:
1. Algorithm
2. Pseudocode
3. Java Code
4. GUI Application output.
