Fast generation of adaptive quadrilateral meshes from range images

This paper proposes a fast technique for generating adaptive quadrilateral meshes from range images with no optimization. The obtained meshes adapt to the features of the input images by concentrating points in areas of high curvature and by dispersing them in low variation regions. This leads to more accurate approximations of the given range images than when uniform sampling with the same number of points is applied. Experimental results with real range images representing both free-form and polyhedral and cylindrical objects are presented.
