Q learning algorithm in image processing using matlab.

I would like to process the images by removing noise from the blur and color correction using Q-learning simpler and more efficient because artificial intelligence and especially deep learning consists of more advanced methods on image processing. I know about neural networks but i don't know much about this algorithm. so, i am totally confused from where to start and how can i do this. Can anyone please share some link because i searched a lot from past two days and i saw most of the videos of q-learning algo is about either games or robot. I can't find any help on image processing side. Please help me, i have also the option of doing this on python.

Hello,

Finding an example that exactly matches what you need to do may be challenging. If you are looking for the "deep learning" version of Q-learning, it's called DQN. See some details here and some examples below.

If you keep finding examples of Q-learning for the application you are thinking maybe there is a reason for that. Without being an expert, Q-learning works with tabular policies, so it may fit nicely with a scenario where you want to manipulate pixels in an image (which is a table after all)

Can i do this Q learning part on "DEEP NETWORK DESIGNER" in matlab?

Actually i have no idea about this app as i didn't work here before, but i will try....thanks

If you were to use DQN (not Q learning), you could use Deep Network Designer to design the critic network if you wanted to. Q learning works with tables so Deep Network Designer is not relevant

So, which app is suitable for Q learning? Because i have to do Q learning and after searching i find out reinforcement learning toolbox used in this. But i haven't free trial.

There is no specific app for Q learning. I would follow the example here to see how to set up the problem
