Spatial Limitations Of Human Stereoscopic Vision

For the design of three-dimensional displays of information obtained in image processing systems it is important to know the spatial resolution of human stereoscopic vision. This knowledge allows presentation of the 3-D information in the format optimal for image visibility, without wasting processing bandwidth on unusable information. (In just such a way, the poor spatial resolution of human color vision was exploited to save transmission bandwidth for color television.) The series of studies reported here establish that the spatial resolution of stereoscopic vision is far poorer than monocular pattern resolution.
