A 3D Index (ΔX3D) for Evaluating Image Quality of Stereoscopic Displays

In stereoscopic displays, crosstalk is typically observed when the views for both eyes are not clearly separated. Crosstalk affects the quality of 3D images and can cause visual fatigue in observers. According to the results of perception experimentation, different visual depth (disparity) and motion blur can also affect the perception of 3D image quality. Therefore, considering the effects of crosstalk, disparity, and motion blur, we propose an evaluation index to quantify 3D image performance for stereoscopic displays. This index assesses the optical quality of a 3D display as well as the effects of image content. According to human vision experimentation, the 3D image index (Delta X-3D) is validated to have a high positive correlation (0.8) with human perception. After combining the human visual mechanism and Delta X-3D, the proposed index can represent the visual quality of static and dynamic images on stereoscopic displays.
