基于 DCT 域视觉显著性检测的图像缩放算法
Image resizing algorithm based on visual saliency detection in DCT domain
摘要
Abstract
In order to meet the requirements of different terminals for various display resolution,the received image need to be resized.However,the coherence of visual contents is easy to be broken among the existing image resizing methods based on content-aware.To address this problem,this paper proposed an image resizing algorithm based on visual saliency detection in discrete cosine transform (DCT)domain.This method utilized a saliency detection model in DCT domain to obtain the sali-ency map.Then it employed the saliency map and the energy map to implement seam carving (SC).The experimental results show that the proposed algorithm can not only protect the important contents,but also guarantee the integrity of visual con-tents,and obtains higher quality index of images by using the proposed method compared with the other content-aware image resizing methods.关键词
