This chapter introduces applications of visual attention models in image processing related areas: just noticeable difference (JND) modelling, visual quality assessment, image and video coding, visual signal retargeting and compressive sensing. Section 8.1 illustrates the combination of visual attention and the JND model towards a complete visibility threshold model which can be used in a wide spectrum of uses. The application of attention models in quality assessment (QA) of images and video is presented in Section 8.2, and a typical QA index, SSIM, is weighted by visual attention in different ways. The use of attention models to explore visual redundancy for better image coding is introduced in Section 8.3. The applications for image retargeting and compressive sensing are presented in Sections 8.4 and 8.5, respectively.
