A perceptual metric for stereoscopic image quality assessment based on the binocular energy
TLDR
A full reference metric for quality assessment of stereoscopic images based on the binocular fusion process characterizing the 3D human perception is proposed and the difference of binocular energy has shown a high correlation with the human judgement for different impairments and is used to build the Binocular Energy Quality Metric (BEQM).Abstract:
Stereoscopic imaging is becoming very popular and its deployment by means of photography, television, cinema. . .is rapidly increasing. Obviously, the access to this type of images imposes the use of compression and transmission that may generate artifacts of different natures. Consequently, it is important to have appropriate tools to measure the quality of stereoscopic content. Several studies tried to extend well-known metrics, such as the PSNR or SSIM, to 3D. However, the results are not as good as for 2D images and it becomes important to have metrics dealing with 3D perception. In this work, we propose a full reference metric for quality assessment of stereoscopic images based on the binocular fusion process characterizing the 3D human perception. The main idea consists of the development of a model allowing to reproduce the binocular signal generated by simple and complex cells, and to estimate the associated binocular energy. The difference of binocular energy has shown a high correlation with the human judgement for different impairments and is used to build the Binocular Energy Quality Metric (BEQM). Extensive experiments demonstrated the performance of the BEQM with regards to literature.read more

Quality Assessment of Stereoscopic 3D Image Compression by Binocular Integration Behaviors
Yu-Hsun Lin,Ja-Ling Wu +1 more
TL;DR: The binocular integration behaviors-the binocular combination and the binocular frequency integration, are utilized as the bases for measuring the quality of stereoscopic 3D images and it is found that the proposed metrics can also address the quality assessment of the synthesized color-plus-depth3D images well.

Depth is encoded in the visual cortex by a specialized receptive field structure.
TL;DR: There is a corresponding anisotropy in the cortical representation of binocular information: receptive-field profiles for left and right eyes are matched for cells that are tuned to horizontal orientations of image contours, and a major modification is required of the conventional notion of disparity processing.

TL;DR: It is concluded that most binocular interaction in striate simple cells may be accounted for by linear summation of neural signals from each eye.
