Application of the Gradient Vector Flow Method for Treating Satellite Image
In this work we propose a new approach to delineate regions in Satellite Image. This method is particularly applicable to the limitation of insoluble habitats. We are interested in detecting the boundaries of the villages near Marrakech from their satellite images, as a study case: Ouahat Sidi Brahim. Our approach has three stages: The first, using k nearest neighbour method for classification of the satellite image. The second, using a mean filter to regularize this classification. In the last we use the Gradient Vector Flow to detect the edge of the village. Our method gives satisfactory and encouraging results to detect the edge of the village and can be used as a tool to control the spread of slums.
Keywords: Classification, Satellite Image, k-Nearest Neighbour ( k-NN), median filter, active contour, Gradient Vector Flow.
