| Abstract: | The finite-element method has become one of the successful solutions to structural mechanics problems in the latest decades. The basic concept of finite-element method is used to interpolate brightness of the image. The triangular element and rectangular element are discussed along with the construction of their interpolation functions (or shape functions). The convergence and error in finite-element solution are also analyzed. An optimal answer to the brightness interpolation is gained finally. |
