Classification: CPC G  H | IPC G  H

Claim 6:
7. The image processing system of claim 1, further comprising a store configured to store group indication data which indicates one or more groups into which pixel values can be grouped,
wherein the processing module is configured to process, in each of a plurality of iterations, a respective pixel value of the stream by operating on a respective spatial subset of pixel values of the stream, in each of the plurality of iterations operating by:
retrieving, from the store, group indication data for at least one group;
using the retrieved group indication data to define the set of groups into which pixel values within the spatial subset can be grouped;
performing said: (i) classifying each of the pixel values within the spatial subset into a group of a set of groups, and (ii) processing the pixel value using one or more of the pixel values of the spatial subset in dependence on the classification of the pixel values of the spatial subset into the groups; and
storing, in the store, group indication data for at least one group of the set of groups, for use in a subsequent iteration.
