Abstract :
Sobel edge detection methode is better than other edge edection methode such as Prewitt
or Robert edge detection methode. If Robert or Prewitt edge detection methode only using 2x2
window on their masking, then Sobel edge detection methode offer to using 3x3 window on his
masking that produce so much better result of detecting edges than other edge detection methode.
How if 3x3 masking that Sobel methode use, we multiply it by a number (0-255) that we can
change intensity of detecting edges with Sobel methode so we can get a better result of an edge
detection.
