| Abstract: | To obtain the change of some objects in remote sensing images of the same region obtained in different time,this paper studied a method of change detection based on the special object extraction.First the special objects were respectively extracted from the two different images according to their geometry feature.Then we got the change of special objects by comparing the difference of two images.Results showed that this method had better effect ondetecting the change of some special objects. |
| Keywords: | image processing special objects change detection geometry feature |
