want to know the techniques that improve black and white images, like i show below plz help me with codes, links , ieee papers etc and techniques names

"improve" is not clear enough for us to respond to. What is a mechanical test we can do in order to determine whether a particular transformed image is "improved" compared to the pre-transform image?

The sample images you have: were they created by lossy wavelet compression relative to fig8 ?

@walter Roberson : i just break the single image into bit plane format , now i want to make it more clear and clean each bit plane image.. yes the main image i choose is of lossy mode

[Walter Roberson]

What is "more clear" in this context? What is "clean each bit plane image" ?

As far as I know it doesn't make sense to denoise each bit plane and them combine them back together again and expect to have a desireable-looking, noise-reduced image. Do you have any theory that says this is a sensible thing to do?

[chitresh]

i think it going to work and nope i dont have any theory of that let me try and let you know

Here's a whole bunch of ways: http://iris.usc.edu/Vision-Notes/bibliography/contents.html

Here's a good online book: http://szeliski.org/Book/

Here's Steve's book: http://imageprocessingplace.com/DIPUM-2E/dipum2e_main_page.htm

The images you attached are just the 8 bit planes of an image. You can just combine they with multiplication and addition to create the grayscale image that they originated from.
