Aircraft image's outline detection algorithm based on image fusion

Region segmentation algorithms can mark the region that has useful information in the image.Thus an edge detection method of region segmentation based on image fusion is proposed.After region segmentation,the region can be gotten which has useful information in the image.Then the edge detection of this region can be conducted through watershed algorithms.The result is fused with the result of other edge detection algorithms and a single-pixel wide and enclosed outline can be gotten.This method can decrease the effect of background on the result of edge detection.It combines the advantages of many algorithms and improves the speed of calculation.The experiment results show that this method is stable,reliable and practicable.
