Set Partitioning In Hierarchical Trees (SPIHT) is an efficient wavelet-based image coding method. It is designed for progressive coding of two-dimensional wavelet transform coefficients by utilizing so called ``parent-children relationship'' among scales. In this paper, we propose a multi-scale graph construction method for graph signal coding using the SPIHT algorithm. In contrast to two-dimensional signals, sampling of graph signals is generally nonuniform which leads to that the SPIHT algorithm cannot be applied straightforwardly. To solve this problem, we propose a method to add dummy nodes to the original graph and adjust the vertex indices so that the multi-scale graph has a binary tree structure. In the experiment, the compression performance and the execution time between the conventional and the proposed methods are compared. The proposed method outperformed the conventional point cloud compression methods in SNR in terms of compression performance. Our algorithm was also faster than the existing SPIHT algorithm for graph signals. |
