In one aspect, multiresolution data pyramids (44) are generated. Each multiresolution data pyramid (44) includes representations of an associated video frame (24) at different respective spatial resolution levels. Each multiresolution data pyramid (44) is stored in a respective discrete frame packet (26). Each frame packet (26) is processed through a sequence of frame packet processing stages generating data (46) that is stored in the corresponding frame packet (26). In another aspect, the multiresolution data pyramids (44) are processed through a sequence of processing stages. Each processing stage performs one or more processes operating at respective variable spatial resolution levels of the multiresolution data pyramids (44). The respective spatial resolution levels at which each process operates are selected.
