between the number of clusters and the corresponding PSNR value when the
Midnight image was used as the cover image.
According to the experimental results, as the number of clusters drops,
the embedding capacity tends to increase, and the PSNR value will decrease
progressively. Since the embedability factor has been taken into account, our
proposed method has a good tradeoff between the embedding capacity and
image quality.
