Image attention retargeting using defocus map and bilateral filter

摘要

In this paper a method is proposed to enhance the saliency of selected region with respect to its surrounding to improve user's attention. Bilateral filter is first used to make the ROI smoother to reduce the unwanted details in the defocus map. Hue component of ROI is adjusted and the outline is extracted using neighbouring data. The outline in resultant image is modified using hue component to direct viewer's attention in a certain region. The proposed method is applied on different natural images and the results are compared with the state-of-the-art existing methods to prove the proposed method's effectiveness.
