Surface modeling is a critical step in three-dimensional (3-D) image processing and understanding. In this paper, a discontinuity-embedded deformable model (DEDM) is developed to model surfaces with discontinuities. Governed by Lagrange motion equation, a finite-element representation of DEDM can dynamically fit the data in both continuous and discontinuous components, when its equilibrium is reached in response to external forces. Experimental results with synthetic and range images show a significant improvement over conventional approaches in preserving depth discontinuities.
