So basically I want to load a picture of a graph and then after the graph changes, it will take another picture from the same position and will tell how does the graph change through the colors of the graph columns(red or white). It will compare the specific pixels that are supposed to get changed to the original picture and by that it will send the answers to a screen. is it possible to do the comparison in arduino and put out the outcome in a screen connected to it. If its not possible or too hard is it better to do it on raspberry pi? Thanks in advance.
It does not sound like this is a suitable project for an Arduino. Probably better on an RP or a PC
I actually think it should be possible, using the Aduino IDE with a SAMD51, a Teensy 3.2 - 3.6, or an ESP32 plus a suitable TFT.
You could do it with an arduino but you would need to start the project and then a few days later you should have your results if you can get enough code into the flash. You will needs lots of external RAM as well. Your best solution would be the latest version of the raspberry pi or a PC. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!

Wouldn’t it be easier to work with the data from which the graphs are generated ?
