Unjuk Kerja Kombinasi Metoda Deteksi Tepi Pada Citra Untuk Menghasilkan Tepi Objek Yang Lebih Jelas(The Performance of Edge Detection Method Combination on The Image to Produce Clear Edge Object)

The edge detection is the operation of image processing which has more important role on image processing, especially on object recognition applications. The edge detection process is a process to find out the differences on the intensity which showing the object limitation of an image. There methods which used to detect the edges of object i.e. Robert operator method, Sobel operator method and Prewitt operator method. Characteristics of an edge detection method sometimes can not provide information about the characteristics of an adequate image so the final result of the image processing is not in accordance with the desired. A combination of two edge detection methods is used in order to detect the object edges of an image with maximum results.
