We describe two studies that were aimed towards increasing our understanding of how the visibility of distortions on stereoscopically viewed 3D images is affected by scene content and distortion types. By assuming that subjects' performance would be highly correlated with the visibility of local distorted patches, we analyzed subjects' performance in locating distortion patches when viewing stereoscopic 3D images. Subjects' performances are measured by whether they successfully locate a local distorted patch, the times they spent to finish the task, and subjective quality ratings given by subjects. The visual data used in this work are co-registered stereo images with co-registered "ground truth" range (depth) data. Varied statistical analysis methods were used to discuss the significance of our observations. Three observations are drawn from our analyses. First, blur, JPEG, and JP2K distortions in stereo 3D images may be suppressed if one of the left or right views is undistorted. Second, contrast masking does not occur, or is reduced, while viewing white noise distorted stereo 3D images. Third, there is no depth/disparity masking effect when viewing stereo 3D images, but there may be (conversely) depth-related facilitation effects for blur, JPEG, and JP2K distorted stereo 3D images.
