Paper Abstract

For 1:1 displays and network visualization in stereo imaging, we suggest that foveation is a feasible and efficient compression method which also gives a good basis for Level of Detail (LOD) control. The demand for highest resolution images in the area(s) of interest is a generally wanted feature, but it is particularly important for photogrammetric 3D modelling where the precision might be highly required depending on the project. Particularly for 1:1 stereo-viewing in large screen displays such as panoramic screens or caves, the actual area of interest is much smaller than the whole screen. Instead of loading the whole image pair, we would foveate both images, and project them after the stereo-foveation. This principally gives us the best possible resolution in the area of interest and still a very good overview of the neighbouring areas to navigate and locate other areas of interest as the human eyes do throughout the non-uniform 3D image. We test the idea with an anaglyph pair, and create a hybrid model by combining algorithms that deal with anaglyph imaging; disparity maps, foveation and we create a LOD function for the resolution control along the z axis.
