CONTRAST
We describe how stereo image pairs can be computed from digital holograms of real-world objects by using a left-side and a right-side window in reconstruction. We also show how the stereo pairs can be displayed on spatially interlaced and anaglyphic of stereoscopic display devices. In addition, we studied the question of how the window size affects the perceptual quality of stereoscopically presented hologram reconstructions. With decreasing window size, the perceived amount of noise increases, the perception of details and the overall perceptual quality of images decreases. Further, we studied the question of how the visual system fuses images shown to the two eyes when the perceived depth of focus is increased by presenting a near-focused image to one eye and a far-focused image to the other eye. The fusion can be described as a spatially weighted mean, where the local contrast of each image is used as a weight. This can be a useful way of extending the depth of focus in stereoscopic presentation of hologram reconstructions.
