How to save an image saved on a Raspberry PI in a variable in order to process the image?

Hello everyone!

I'm trying to do a Image Processing project using Matlab and deploy it on a Raspberry PI. I want to take the photos with a systemcall on the PI and save it on the PI. Now the question: How can I save a image (saved on the PI) in a variable in order to process the image? And how to delete the image each new iteration?

The function has to be deployed on the PI - so imread is not possible for example.

Thanks in advance.

Hey, thanks for your response - could you explain your solution a bit more detailed? So you mean to setup a http server on the PI and how can I read the image then?

[yanqi liu]

yes，in PI，use python flask to make http server，in computer use imread to get image by http url

ohh i forgot to mention that I wanna use the PI as a standalone so cant deploy imread...
