Adaptive recursive image filtering

An edge preserving smoothing filter for images distorted by additive noise is developed as an example of recursive adaptive filtering. The filter attempts to minimize the local squared-error in each neighborhood of pixels. Its performance is compared to the original nonrecursive version of the same...

Summary:An edge preserving smoothing filter for images distorted by additive noise is developed as an example of recursive adaptive filtering. The filter attempts to minimize the local squared-error in each neighborhood of pixels. Its performance is compared to the original nonrecursive version of the same filter.< >
