WebComplexes, topological objects that ﬂexibly subsume SCs and graphs. We show that this generalisation provides a powerful set of graph “lifting” transformations, each leading to a unique hierarchical message passing procedure. The resulting methods, which we collectively call CW Networks (CWNs), are strictly more Weboptimize edge weights for the graph to be used for our graph-based lifting transform. For intra-prediction, we propose a novel intra-prediction strategy designed for sparsely distributed pixels in SAIs. Speciﬁcally, we ﬁrst estimate the local characteristics, e.g., object contour, of each block based on structure tensor [35], dye free infant motrin
