Influence of significant target on image quality assessment via EEG

The significant target in the image shows how much people pay attention to certain objects in the image when viewing the image. These significant targets will affect human perception of image quality when quality change occurs. But in recent years, most of the image quality perception research based on elsctroencephalography(EEG) were not considered of these significant targets. Therefore, this paper obtains the EEG signals of the subjects through an image rendering experiment for the presence or absence of significant targets, and compares the signal differences. The experimental results show that there is no significant effect on the image quality perception in the perceptible range. If there is a large degree of distortion, whether there is significant target has an important impact on the image quality perception.
