noise detection filters like median filter is not useful for random value impulse noise. How RVIN can be detected?
Hello dear Nisar,
Check this link and the attached materials. I wish that can help you.

If the median filter is not effective, then I recommend first assessing the type of noise in the image to make sure if it is really impulse. Try to find a relatively homogeneous texture area in the image and measure the noise therein (by fitting to different noise models).
The papers below apply this simple technique to measuring noise in lung tumor CT images, which can be used on other types of images as well:
- O. S. Al-Kadi, “Assessment of texture measures susceptibility to noise in conventional and contrast enhanced computed tomography lung tumour images,” Computerized Medical Imaging and Graphics, vol. 34(6), pp. 494-503, 2010.
- O. S. Al-Kadi and D. Watson, “Susceptibility of texture measures to noise: an application to lung tumor CT images,” in 8th International Conference on BioInformatics and BioEngineering, Greece, pp. 1-4, 2008.
Dear Shafaq,
I enclose for you a paper includes a compassion of different de-noising filters applied for medical images.
Good Luck.

The Adaptive Noise Detector is used to detect the type of noise such as Gaussian noise, salt and paper and so on, if exists in the current image.
