Application of Mathematical Morphology in the Skeleton Extraction of Spatial Pattern Image

Mathematical morphology is a powerful implement in the research of image analysis.It has been a primary domain of image science and its theory and method has been applied in many fields.The article is to study its method in the process of extracting the skeleton of spatial pattern based on remote sensing data.Spatial pattern image differs from area with slab-sided shape such as character and fingerprint.It is not slab-sided with daedal orientation.The authors sum up the current major mathematical morphology arithmetic of thinning at first.They find out the merits and demerits by analysing the difference between these arithmetic using the resultant contrastive photos.Finally, based on these arithmetic, the authors bring forward an improved arithmetic of skeleton extraction of spatial pattern image that is very fit for not slender bar with large area, furthermore offer the realization method for the program.
