Stable algebraic surfaces for 3D object representation
Sahin, Turker and Ünel, Mustafa (2008) Stable algebraic surfaces for 3D object representation. (Accepted/In Press) AbstractLinear fitting techniques by implicit algebraic models usually
suffer from global stability problems. Ridge regression
regularization can be used to improve the stability of algebraic
surface fits. In this paper a Euclidean Invariant 3D ridge
regression matrix is developed and applied to a particular linear
algebraic surface fitting method. Utilization of such a
regularization in fitting process makes it possible to globally
stabilize 3D object fits with surfaces of any degree. Robustness
to noise and moderate levels of occlusion has also been enhanced
significantly. Experimental results are presented to verify the
improvements in global stability and robustness of the resulting
fits. Available Versions of this ItemRepository Staff Only: item control page
