Interpolating Intermediate Views of Stationary Objects

View interpolation has many applications in 3D graphics, visualization, animation, and image sequence compression. I present an implementation of a particular interpolation scheme, proposed by M. Hansard and B. Buxton in Proc. 6th European Conference on Computer Vision (I), 191-202. 2000. [1]. Given two images of an object, this method can synthesize intermediate views without explicit reference to the camera or scene geometry. All that is required is two basis views and the linear relationship between combinations of affine projections of an object. By fitting polynomial models to the parameters of this relationship a simple and effective synthesis results. While [1] dealt mainly with theoretical aspects and proof of concept, this work represents an interactive implementation of the complete algorithm. Particular attention was paid to non-trivial rendering issues such as handling of hidden surfaces. Some original methods of reducing rendering artifacts in the synthesized views are presented in conclusion. The result is a simple application tool for comparing parametric interpolation with morphing plus an analysis of the algorithm’s performance on real world examples.
