Paper Abstract

In this paper we present three image processings intended to limit eye strain when using stereoscopic displays. These processings are based on a compatibility of the disparity in the image and of the local spatial frequency: to measure this compatibility, we introduced a stereoscopic comfort function. According to the value of the function, one point in the image is processed or not. We suggest three filterings (a 'Virtual Curtain,' a 'Virtual Pane' and an 'Adaptive Haze') that hide the points behind a gray curtain, a frosted pane or a kind of aerial perspective haze. These three processings were applied to synthetic images and presented to subjects in a human factors experiment. Whereas the less flexible processings ('Virtual Curtain' and 'Virtual Pane') were not very convincing, the 'Adaptive Haze' proved to be more comfortable than the two others, and even more than the original images to a large extent.
