WebGraph-based Transform (GT) has been recently leveraged successfully in signal processing domain, specifically for compression purposes. In this paper, we employ the GBT, as well as the Singular Value Decomposition (SVD) with the goal to improve the robustness of audio watermarking against different attacks on the audio signals, such as …
WebDec 18, 2024 · In this paper, we propose a new graph-based transform and illustrate its potential application to signal compression. Our approach relies on the careful design of a graph that optimizes the overall rate-distortion performance through an effective graph-based transform. We introduce a novel graph estimation algorithm, which uncovers the … WebSuppose we need to graph f (x) = 2 (x-1) 2, we shift the vertex one unit to the right and stretch vertically by a factor of 2. Thus, we get the general formula of transformations as. f (x) =a (bx-h)n+k. where k is the vertical shift, h is the horizontal shift, a is the vertical stretch and. b is the horizontal stretch.
WebThis paper presents a novel class of Graph-based Transform based on 3D convolutional neural networks (GBT-CNN) within the context of block-based predictive transform coding of imaging data. The proposed GBT-CNN uses a 3D convolutional neural network (3D-CNN) to predict the graph information needed to compute the transform and its inverse, thus … WebSep 1, 2024 · The second approaches, GNNs with relation-based graph transformations, generally utilize meta-paths. The Heterogeneous Graph Attention Network (HAN) (Wang, Ji, et al., 2024) first transforms heterogeneous graphs into homogeneous graphs using manually selected meta-paths and applies an attention-based GNN on the graphs. …
