Figure 20

The one-dimension logarithm power spectrum of the Mars image. (a) The red, green, and blue curves represent the one-dimension logarithm power spectrum of original image, 10 original image superimposition, and 10 images processed by the proposed method superimposition, respectively; (b) the red, green, and blue curves represent the one-dimension logarithm power spectrum of 3 images, 5 images, and 10 images processed by the proposed method superimposition.
