Graph lifting transform
WebIn this work, we extend recent theoretical results on SCs to regular Cell Complexes, 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. WebThe figure gives the table of cumulative values of the class 1 classifications and the corresponding lift chart. The dashed line joining the points (0,0) to (24,12) is a reference …

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], Webwavelet transforms, Fourier-based and wavelet-based graph filters, and lifting structures. In SectionIV, we present the proposed lifting-based adaptive graph wavelet filters and its properties (i.e., locality, sparsity, and vanishing moments). In SectionV, lifting-based adaptive graph wavelet networks are developed for permutation-invariant ...

The transform has been applied previously with promising … WebAfter defining a graph, the graph signals, i.e., the residual pixel intensities, are encoded using a graph-based lifting transform [23]. In our experiments, we apply the proposed LF...
