What is the filter to get a heavy metal film ilustration?
There are two techniques that can achieve similar results, but if you caught that in a recent paper then you are probably after Style Transfer.

It is based on "teaching" a neural network how to combine specific elementary features in one context (e.g. Renaissance paintings) and then applying them in a different context (e.g. some random picture).

The other technique is "Colour Transfer" (or "image re-colouring") and that one attempts to copy just the colour tones and overall "feel" from one image to another but without changing the structure of its content. Here is a good overview and a particular method of applying it.

Hope this helps.
