1. A method of filtering a target pixel, comprising:
calculating a weight for each pixel of a kernel of pixels comprising the target pixel, the weight for each pixel comprising a data term dependent on a pixel value of that pixel and its predicted pixel value according to a data model that models pixel values within the kernel; and
using the calculated weights for the pixels in the kernel to form a filtered pixel value for the target pixel.
