i am trying to write a program (preferably with arduino uno but can use a mega if needed) to detect the change between two images (attached below) I need to see changes in color and shape, and highlight or circle them somehow. We are using a random car backup camera, and I am not able to buy a pixy. If someone could help me it would be great!
The Arduino Uno and Mega do not have enough memory to do anything useful with images.
For about USD 10 you can buy the ESP32-CAM, which does.
Better, use a laptop with ImageJ (free to download).
I do not think that an Uno or a Mega has enough processing power and/or memory to do what you want. Maybe a Rpi?
If the images are lit & registered perfectly, you can save an image or hash of the image, and XOR them over time.
Any changes will be easily identifiable.
If you want specifics of what changed, you’ll need to do more work.
