Help for my projet on Computer Vision

Hello all,

I would like to set up an algorithm that can detect the appearance of a pop-up on the local PC.

I have in my possession a test, training and validation dataset

I have from you a support to start my model ie what type of model used? Which algorithm used?

At the end of the algorithm, As soon as a pop-up corresponding to an anomaly is displayed, it must be detected and correctly classified by our module.

If someone from this community has already worked on this kind of subject, thank you for enlightening me and we can discuss.

Thank for all
