I am looking for methods to enhance noisy images, where:
- some pixels in the image are very noise,
- some other pixels do not contain so much noise.
My first thought is to build an adaptive Gaussian filter. This means that the Gaussian kernel will depend on the (estimated) noise status of the current pixel (large radius of the Gaussian kernel for noisy pixels and a smaller in the converse case).
Could you help me in calculating the kernel values?
