Title
Quality Assessment Of 3d Visualizations With Vertical Disparity: An Erp Approach
Abstract
In an objective approach for the assessment of quality of experience the neural correlates of EEG data are studied when stereoscopic images are presented in three different conditions containing vertical disparity. These conditions are compared to a similar image in 2D both on the channel level by studying the ERP components and on the source level by the localization of the corresponding ERP component. Our findings posit that P1 component in the occipital cortex has significantly increased in amplitude for 3D condition without vertical disparity compared to the 2D condition. According to previous studies, this component increases when depth information are added to the stimulus which is in line with our findings. However the amplitude of this component has significantly decreased for 3D condition with maximum vertical disparity compared to the 3D condition without vertical disparity. We have concluded that the perception of stereoscopic depth by subjects have decreased in this case due to the distortion introduced by vertical disparity. The underlying sources corresponding to P1 component are localized. Except for the power differences, the source locations do not differ for different conditions.
