This is a tutorial about how to write a simple code in Python to show the differences between 2 images.
Although It’s a crude code this can be very useful for practicing fundamental programming skills. You can also find a more elegant approach here. (soon to be published.)
In something like 25 lines of code you can see the demonstration of:
for loops, PIL library usage, manual counter (c), conditional expression (if – else), continue / break statement and data array subtraction (numpy).
