Edges Extraction with Mathematical Morphology Tools and Canny Filter: A Comparison

A comparative Mathematical Morphology tools with Canny filter is developed for extracting edges with IKONOS-2 satellite PCA fused image of Cavouco’s lake of the campus of Federal University of Pernambuco (UFPE). MATLAB was used for extraction edge with Canny filter. To obtain the gradient, the inner edge and the outer edge of the lake, with Mathematical Morphology (MM), the SPRING software was used. Moreover, to obtain the profiles to perform the comparison among the edges, ENVI’s software was used. MM defines internal or external edge of the object and Canny identify only the outside edge of the objects.
