Frequency dependent interpolation for image based models

We present a novel perception based technique of texture interpolation for view dependent projective texture mapping of image based models. When interpolating projected texture maps, regions of texture incongruence can generate artefacts. Non congruent texture regions are the result of unmodelled features in the geometric scene model. We show how a perception based metric can be used to control the interpolation process and reduce these artefacts. The metric, based upon the human perception of Mach bands, is also used to evaluate the new interpolation method against current techniques.
