Photo assessment based on computational visual attention model

Abstract

It is difficult to be satisfied for automatic photo assessment using only low level visual features such as brightness, lighting, hue, contrast, color distribution and so on. Instead of using low level visual features, we present a novel computational visual attention model to assess photos. Firstly, a face-sensitive saliency map analysis is deployed to estimate attention distribution. Then, a Rate of Focused Attention (RFA) measurement is proposed to quantify photo quality. By integrating top-down supervision into the visual attention model, we further achieve personalized photo assessment to take user preference into quality evaluation, which can be extended into object or semantic oriented photo assessment scenarios. Experiments on personal photo albums with comparison to ground-truth user evaluations demonstrate the effeteness of the proposed method.
