Joint adaptation of spatial resolution and sample value quantization for asymmetric stereoscopic video compression: A subjective study

Abstract

A novel asymmetric stereoscopic video coding method is presented in this paper. The proposed coding method is based on uneven sample domain quantization for different views and is typically applied together with a reduction of spatial resolution for one of the views. Any transform-based video compression, such as the Advanced Video Coding (H.264/AVC) standard, can be used with the proposed method. We investigate whether the binocular vision masks the coded views of different types of degradations caused by the proposed method. The paper presents a subjective viewing study, where the proposed compression method is compared with two other coding techniques: full-resolution symmetric and mixed-resolution stereoscopic video coding. We show that the average subjective viewing experience ratings of the proposed method are higher than those of the other tested methods in six out of eight test cases.
