Investigating symmetric and asymmetric stereoscopic compression using the PSNR image quality metric

Context: In this paper we will assess the two different stereoscopic image compression methods, symmetric and asymmetric encoding. As stereoscopic images require an increase in storage space compared to monoscopic images, the compression of stereo images is one of the most important factors to enable the extensive use of three-dimensional systems. Substantial research effort has been focused on digital image compression using JPEG, however, the question of how much compression to apply and the most appropriate compression method to use still remains unresolved [1].
