Intuitionistic fuzzy bicubic Bézier surface approximation

Surface and their description plays an important role in design, physical, geology and other natural phenomenon. In this paper, intuitionistic fuzzy Bézier surface approximation that considers bicubic case with 4×4 control net is introduced. The intuitionistic fuzzy control net relation is defined through intuitionistic fuzzy concept. Later, the control net is blended with Bernstein basis function to obtain surface blending function and to produce intuitionistic fuzzy bicubic Bézier surface. Lastly, the intuitionistic fuzzy bicubic Bézier surface is illustrated through the approximation method by using data point with intuitionistic features.
