How to make a neural network to change the image?

Question

Python

I'm starting to study neural networks and I have a question. Let's say I have pictures that I want to change according to the drawing. For example, to make the lines clearer. Do I need to manually change them first, and then feed the original image and the modified one to the input in order to train or how?

Answer 1

Yes, and you need to submit a couple of thousand of such pairs "original" - "modified" to train the network.
Only here "make a neural network" and "train a neural network" are completely different concepts.

Answer 2

A couple of thousand pieces will not be enough, to be honest. Especially considering that the size of the input image for a neural network is most often fixed.
For such a task, you can do without a neural network.
And if it is with a neural network, read the material on convolution networks, for starters.
