is there any better way to remove structured noises from latent fingerprints ?

As the total variation model does not remove characters from latent fingerprint, is there any better way to remove structured noises from latent fingerprints ?

[Merged from duplicate]

When I extract texture component from the latent fingerprint,the structured noises such as characters and numbers is not removed from the latent fingerprint. I need to extract only the fingerprint content from the image leaving the structured noises as cartoon component. Is there any better method for doing the same.

You might try CLAHE, which is done with the adapthisteq() function.
