results of a new technique for 2D-to-3D conversion

The complaints voiced by Gunnar concerning difficulty foveating vertical (or any non-horizontal) disparities is most commonly expressed by older viewers- mostly over 60-65 years.

Most viewers from teens to 45-50 have no problems with foveation of the range of vertical to horizontal disparities found in 3D conversions of many sorts based on geometric transformations.

This assumption is very, very wrong.

The vertical disparities are well known to induce severe discomfort (proportional to the level of disparity), independent of the viewer's age.

Detection of vertical disparity in three-dimensional visualizations

"The desirable value of the above mentioned displacement (vertical disparity) is zero. It means that the image is correct with regard to the disparity issue. If the value does not equals zero(h), the image contains the disparity error. User may properly interpret the three-dimensional visualizations only if the objects from their stereo pair have no vertical displacement. Occurrence of this artifact precludes proper image receiving. The defect has a negative impact on the product quality, but also may results in serious health consequences in the case of longer exposure of the viewer to the discussed anomaly. The only way to avoid such problems is to conduct precise tests of 3D visualizations in order to detect visual artifacts, especially the vertical disparity. Defects connected with the occurrence of the disparity have to be entirely eliminated before releasing the product."

Hi, Gunner,

Sorry, but you are in serious need of an update in the literature on vertical disparities and binocular depth perception. Here’s a brief selection that will get you started.

Best regards,
