Abstract :
On the premise that the texture image is planar surface, we present a new morphological approach to obtain a 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 an entire texture image is segmented into several sub-regions. Using the major axes and the size of structuring elements in segmented regions, we can compute the vanishing point and obtain the 3-D surface orientation. In the experimental results, we have ascertained the proposed algorithm was more effective than the aggregation transform
