highly similar to ones used by prior art, to which we compare against.

The images are labelled within 27 different styles (cubism, rococo, realism, fauvism, etc.), 45 different genres (illustration, nude, abstract, portrait, landscape, marina, religious, literary, etc.) and belong to more than 1000 artists. To our knowledge this is the largest database currently available that contains genre annotations. For our tests we considered a set that contains 79434 images of paintings.

In WikiArt some of the genres were not well represented (i.e. less than 200 images) and we gathered them into a new class called “Others”. This led to a division of the database into 26 classes illustrated in Figure \[Fig:Database\]. The names of the classes and the number of training and testing images in each class can be seen in Table \[Tab:Genre\_Explain\]. Furthermore, as the genre label is not explained in prior works, we also contribute with an explanation of the genre meaning; these explanations are collected from an Internet encyclopedia[^4].

The list of genres that counted less than 200 examples and are included in the ”Others” class contains, among others: ”advertisement” – 94 examples – illustrate a work of art designed to market a product; ”capriccio”(194) –
