Abstract

We present a novel technique for interpolating between two views of a dynamic scene. Our approach extends the concept of view morphing introduced in [SD96] and retains the relative advantages of that method. The interpolation will portray one possible physically-valid version of what transpired in the scene during the intervening time between views. The scene is assumed to consist of a small number of objects. Each object can undergo any motion during the time between views as long as its total movement is equivalent to a single, rigid translation. The dynamic view morphing technique can work with widely-spaced reference views, sparse point correspondences, and uncalibrated cameras. When the camera-to-camera transformation can be determined, the virtual objects can be portrayed moving along straight-line, constant-velocity trajectories. Methods are developed for determining the camera-to-camera transformation from information available in the reference views. It is shown that each mov...
