Claim 15:
16. The pixel filter of claim 1, in which the filter module is further arranged to perform a further recursive filter operation in a further direction through the sequence of pixels, different to the particular direction, so as to form a further filtered pixel value for each pixel in dependence on the pixel value at that pixel and contributions from two or more other pixels in the sequence of pixels, the further filtered pixel value for the preceding pixel being scaled by more than one further measure of similarity between data associated with that pixel and the two or more other pixels;
the filter logic being further configured to generate the filter output for each pixel of the sequence in dependence on a combination of:
the filtered pixel value for that pixel formed by the recursive filter operation, and
the further filtered pixel value for that pixel formed by the further recursive filter operation.
