Clustering of an image by taking into account the spatial context of each pixel (besides its intensity)

Thanks for your answer, this seems to be a nice algorithm for the denoising
But actually I'm looking for an image clustering (segmentation) technique
instead (that would take into consideration the spatial context of pixels).
