Aesthetic enhancement of landscape photographs as informed by paintings across depth layers

This paper addresses the aesthetic enhancement of contrasts in saturation and luminance in a landscape photograph to follow the organization of such contrasts in landscape paintings. Different from many existing work on similar topics that mainly emulate the surface characteristics of a painting, this paper presents a technique that transfer the contrast organization in landscape paintings inter and intra four depth layers onto landscape photographs. The contrasts in saturation and luminance revealed in landscape paintings along the scene depth provide the references to guide the mapping of such contrasts in photographs. A novel inter and intra depth layer luminance and saturation contrast mapping algorithm using gradient histogram matching is developed. Experimental results demonstrate the effectiveness of the proposed method.
