3D Shape Modelling through a Constrained Estimation of a Bicubic B-spline Surface
This paper presents a new method to extract the 3D shape of objects from 3D gray level images using a bicubic B-spline surface model. Extraction of object shape is achieved throug...

Spiraling Edge: Fast Surface Reconstruction from Partially Organized Sample Points
Many applications produce three-dimensional points that must be further processed to generate a surface. Surface reconstruction algorithms that start with a set of unorganized poi...

On the Use of Gradient Space Eigenvalues for Rotation Invariant Texture Classification
Many image-rotation invariant texture classification approaches have been presented previously. This paper proposes a novel scheme that is surface-rotation invariant. It uses the ...
