Multiresolution analysis (MRA) over graph representation of EEG data has proved to be a promising method for offline brain-computer interfacing (BCI) … 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],

Suitable edge weights are assigned to reflect similarities between connected sample pairs, and the graph-signal is encoded using a graph-based lifting transform proposed in [10]. The transform has been applied previously with promising results for image compres-sion …

WebOur second integer spectral graph transform is achieved by introducing rounding operations within the spectral graph lifting structures proposed in Reference [34]. Hence, we transform it into an integer-to-integer graph wavelet transform. Using our proposed transforms mentioned above, we design a lossy-to-lossless extension to
WebIt is noteworthy that the proposed graph architecture makes the application of a graph lifting transform straight forward. As in any lifting transform we need to define the split, predict and update steps. The split step is defined over the node set by using the parity of t. The even vertex set V
