OBTAINING A 3-D ORIENTATION OF PROJECTIVE TEXTURES USING A MORPHOLOGICAL METHOD

摘要

On the premise that the texture image is a planar surface, we propose a new morphological approach to obtain a 3-D surface; orientation using the variation of texture image caused by projective distortions. Centroids of texels can be obtained from the farthest texel to the nearest texel sequentially by recursive erosions, so a texture image is segmented into several sub-regions. Using major axes and sizes of structuring elements in segmented regions, we can compute a vanishing point and obtain a 3-D surface orientation. In the experiments, we have ascertained the proposed algorithm was more effective than the aggregation transform. [References: 16]
