Abstract

Current binocular stereoscopic displays cause visual discomfort when the objects with large disparities are present in the scene. With this technique, the improvement of visual comfort has been reported by blurring far background and foregrounds in the scene. However, this technique has a drawback of degrading overall image quality. To lesson visual discomfort caused by large disparities while maintaining high-perceived image quality, we use a novel disparity-based asymmetrical filtering technique. Asymmetrical filtering, which refers to the filtering applied to the image of one eye only, has been showen to maintain the sharpness of a stereoscopic image, provided that the amount of filtering is low. Disparity-based asymmetrical filtering usese the disparity information in a stereoscopic image for controlling the severity of blurring. We investigated the effects of this technique on stereoscopic video by measuring visual comfort and apparent sharpness. Our results indicate that disparity-based asymmetrical filtering does not always improve visual comfort but it maintains image quality.
