Abstract:
In this poster we describe preliminary work relating the perception of scale (the variance parameter in scale-space filtering) with distance, for applications in 3D online visualization. 3D geometry and texture simplification can be based on scale-space analysis of the surface curvature and feature point distribution, to facilitate online transmission. The scale-space approach differs from other simplification approaches [1,2] in that a few parameters can be used to mathematically control the extent of simplification, and joint texture/mesh simplification is possible with a trade-off between texture and mesh transmission. We will outline our approach to joint TexMesh simplification (differing from purely surface simplification [3]) using scale-space filtering, followed by a description of how scale is perceived by human observers for 3D objects.
