A Visual Comfort Assessment Metric for stereoscopic Images (ICIP2015)

A visual comfort evaluation criterion for stereoscopic images

The adjustment accommodation corresponds to the monocular focus process and is modeled as the joint entropy of the left and right views. Focus Vergence is equivalent to the binocular fusion process, modeled as the mutual information of the left and right views. The joint entropy and mutual information are calculated from the visual primitives extracted from the left and right views, and the adjustment-focus conflict is expressed as the ratio of mutual information and joint entropy.

As oculomotor nerve clues, regulation is a monocular clue that refers to the lens shape and thickness of the change (focal length), which makes the eye focus at a specific distance of the object. Focusing is a binocular clue, which refers to the muscle rotation of the eyeball, which is used to gather two eyes on the same object. So the adjustment is equivalent to the focus process, which maintains a clear view of the image. While focusing is equivalent to the fusion process, the binocular retina image is fused to a perceptual image. In the proposed SVCA criterion, the adjustment is expressed as the clarity of the left and right views, measured by their visual perception information and modeled as joint entropy. The focus is expressed as the fusion of visual perception information between the left and right views, modeled as mutual information. Joint entropy and mutual information are calculated from the visual primitives extracted from the left and right views through a dictionary learning algorithm, and then the adjustment-focus conflict is expressed as mutual information/joint entropy.

In sparse representations, for a given image, the base unit is a patch.
