What computer vision task does describing the features of images comes under?

I have a very noob question - Is there a computer vision task category for the task when you describe the objective feature of the images like - brightness, focus, artefacts and hence classify the image in a certain category.
It would come under classification with localisation if we were drawing the bounding box around the object but in this case one can't physically locate brightness, focus and artefacts, these are features of the images.
Is there a task category which this falls under?
