Image denoising using Bilateral filter in high dimensional patch-space

This paper proposes a new noise filtering method inspired by Bilateral filter (BF) and non-local means (NLM) filter. The main idea here is to perform the BF in a multidimensional patch-space using an anisotropic kernel. The filtered multidimensional signal is then transformed back onto the image spatial domain to yield the desired enhanced image. The proposed method is compared to the state-of-art. The obtained results are highly promising.
