Visual information has become an effective medium of communication for

people across the globe. Rather, it has become an essential ingredient to convey

information. An image as a media of communication is possible only when its perception

is determined by humans. In the field of photography, aesthetics is perceived as an

appreciation of beauty in an image or a photograph. This paper presents an organized

review of the prevalent literature on image aesthetics. Initially, we discuss the low-level,

middle-level, and high-level image attributes with their aesthetic contributions; this is

followed by ways to bridge the existing semantic gap between them. We further elaborate

on the existing computational frameworks, which are used in literature for image

aesthetics evaluation and enhancements. We conclude by providing an extensive

discussion of our interpretation of the literature survey.
