| Abstract: | Shadow detection in high spatial resolution remote image is very critical for target identification and information recovering.In this paper,an object-oriented method is used to detect shadow area.Firstly,the image is processed by segmentation to attain the image objects,then the knowledge is established according to the analysis of the spectral character of the shadow area in the image.Finally,the shadow area could be extracted by using the rules defined in the knowledgebase.The experiment result shows tha... |
