《Saliency Detection: A Spectral Residual Approach》是上交高材生侯晓迪在07年的CVPR上发表的一篇论文，这篇文章提出了一个图像视觉显著性的简单计算模型，这个模型和Irri提出的模型是两个截然不同的模型，Irri模型对于图像视觉显著性主要关注整幅图片突出的部分，通过各种特征的融合提取显著性图，而Hou的这个模型一上来关注的点就不在一张图片里突出的地方，而是背景，观察是否大部分图片的背景在某个空间上都满足什么变化，最后剔除背景，自然就只剩下图片突出的部分了-" Saliency Detection: A Spectral Residual Approach"　is turned on in the top students HOU Xiao Di 07 years CVPR paper published, this article presents a significant visual image of a simple calculation model, the model and the model proposed is two Irri distinct model, Irri model for the image saliency focused on the entire picture projecting portion extracted by the integration of the various features saliency map, and Hou this model up a point of interest in a picture is not prominent in place, but the background to observe whether the majority of the background image on a space to meet any changes, and finally removing the background, naturally, only the image projecting part
