I have a mixed image database(unstructured data). In the database there are some images that i am interested in and I want to discard the rest by using cnn. I am not looking for specific objects in the images like dogs, cats etc. In the database I have photos and non photo images like infamous logos, scanned documents etc.
I want to find photos and discard the others. All the examples and online courses I found are based on object recognition. In my case which method can I use to classify my images as just 'relevant' and 'irrelevant'?
