| Abstract: | The reasoning of inverse direction relation on two dimensional regions is the important measure in spatial relationing area. By using the connection of MBR and direction relation matrix, the method of computing the inverse direction relations based on MBR and rectangle algebra is introduced, and the method of computing the inverse direction relations based on matrix is given. |
