View Morphing: Uniquely Predicting Scene Appearance from Basis Images

This paper analyzes the conditions when a discrete set of images implicitly describes scene appearance for a continuous range of viewpoints. It is shown that two basis views of a static scene uniquely determine the set of all views on the line between their optical centers when a visibility constraint is satisfied. Additional basis views extend the range of predictable views to 2D or 3D regions of viewpoints. A simple scanline algorithm called view morphing is presented for generating these views from a set of basis images. The technique is applicable to both calibrated and uncalibrated images.
