Extended Closing Operation in Morphology and Its Application in Image Processing

According to the practical demands of stitching and analysis of post-earthquake UAV aerial images, we extended the closing operation in mathematical morphology, brought forward the concept of extended closing operator and its formal definition. Algorithm is designed and software development for the algorithm is implemented by using VC++ 6.0. The correctness of the algorithm for extended closing operation has been demonstrated by experiments results. Performance of the system with real image demonstrated that the opening operation proposed in this paper extended functions of opening operation of mathematical morphology and is of theoretical significance and practical values.
