Show water with three-dimensional sense. This method does not produce a true three-dimensional image, but rather gives the viewer a different view of each eye to provide a three-dimensional effect, never making the scene with depth. To get a three-dimensional projection, you first need to get two views of the scene from the observation direction relative to each eye (left eye and right eye). You can obtain both views by specifying a different observation location and by a computer-generated scen
A visual comfort evaluation criterion for stereoscopic imagesThe 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
