Robust Estimation of Multiple Surface Shapes from Occluded Textures - Computer Vision, 1995. Proceedings., International Symposium on

This paper examines the problem of estimating surjiace shape from texture in situations in which there are multiple textures present due to texture discontinuities, occlusion, and pseudo-trarzspareizcy (fbr example looking through a picket fence ut u textured s u @ ~ e ) . Previous shupe-ji-om-texture methods that use changes in the spatial jrequency representution ofneighboring image patches u m m e that only a single texture is present in each of the patches. We extend these upproaches to situations in which multiple textures muy be present. We provide a theoretical analysis ofthe multiple texture problem and the effect of texture discontinuities, occlusion, etc. on the spatial .frequency representution. We ulso present un algorithm, using robust mixture models, jijr recovering multiple surjace shapes from occluded texturex The methodpeforms well on real and synthetic inzages with results which ure comparable to that of shupefiom texture with only one texture.
