This Paper described a new algorithm for round contour extraction of indent image on metal surface after Brinell hardness test. Morphological theory was employed to extract round contour of indent image effectively. Based on characteristic of grayscale image, structural element was chose according to its shape feature and grayscale feature in order to acquire better result. Before the stage of contour extraction, fuzzy theory was employed to enhance indent image. Validity of this approach is demonstrated using several indent images.
