| Abstract: | Aim at the visualization expression of grid data computation,a grid data map finite element adaptive subdi-vision method is presented.Then an information fusion edge detection algorithm based on grid computation and digital image processing is proposed.Using this method,the numerical computing is adjusted automatically to the character area.The experiment results show that the sample resolution of the grid computation can be greatly improved without increas-ing the numerical computation very much. |
