Description
Summary:The bandwidth required to transmit stereoscopic video images is nominally twice that required for standard, monoscopic images. One method of reducing the required bandwidth is to code the two video streams asymmetrically. We assessed the perceptual impact of this bandwidth-reduction technique for low-pass filtering, DCT-based quantization, and a combination of filtering and quantization. It was found that the binocular percept depended on the type of degradation: for low-pass filtering, the binocular percept was dominated by the high-quality image, whereas for quantization it corresponded to the average of the inputs to the two eyes. The results indicated that asymmetrical coding is a promising technique for reducing storage and transmission bandwidth of stereoscopic sequences.
