Computer Vision

Can the new Arduino Giga be capable of doing computer vision processes?
Like facial expression recognition and that sort of thing, I know for a fact that the other versions of Arduino boards do not have the processing power to do computer vision but with two ARM processors I think they should be sufficient enough.

What are your thoughts?

You also need enough RAM memory to store the images while being processed.

I can add extra memory to the Arduino Giga right?

How much do you need, and what does the Arduino Giga documentation state?
