The method of depth map calculation based on soft operators

The fuzzy method of depth map calculation using stereo images based on SAD (Sum of Absolute Differences) algorithm composition and fuzzy inference is considered. The feature of this method is soft arithmetic operators with fuzzy implication usage. The accuracy of the method of depth map construction is estimated by RMSE (root mean square error). The best soft operator has minimum RMSE. The method of depth map calculation which has 7 steps is presented. The proposed method showed that the accuracy of the SAD algorithm increases by 20% when soft operators are used. This conclusion is confirmed by the simulation results presented in the article.
