Mathematical Morphology for Color Images: An Image-Dependent Approach

Figure 6

Real image “dragon” (a) with its erosion (b/f), dilation (c/g), opening (d/h), and closing (e/i) with a disk of radius 3 pixels. Method of Angulo in the RGB (b to e) and 𝐿^∗𝑎^∗𝑏^∗ (f to i) spaces choosing black as the reference color.
