Set Partitioning in Hierarchical Trees for Point Cloud Attribute Compression [PDF]
IEEE Signal Processing Letters, 2021 <div>We propose an embedded attribute encoding method for point clouds based on set partitioning in hierarchical trees (SPIHT) [1]. The encoder is used with the region-adaptive hierarchical transform [2] which has been a popular transform for point cloud coding, even included in the standard geometry-based point cloud coder (G-PCC) [3],[4].

Comparison of Effects of Entropy Coding Schemes Cascaded with Set Partitioning in Hierarchical Trees
Mehran University Research Journal of Engineering and Technology, 2018 WT (Wavelet Transform) is considered as landmark for image compression because it represents a signal in terms of functions which are localized both in frequency and time domain.

2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698), 2003 The paper proposes a technique for scalable to lossless audio compression. The scheme presented is perceptually scalable and also provides for lossless compression. It produces smooth objective scalability, in terms of SegSNR, from lossy to lossless compression.

Modified set partitioning in hierarchical trees algorithm based on hierarchical subbands [PDF]
Journal of Electronic Imaging, 2015 This paper introduces a modified set partitioning in hierarchical trees (SPIHT) algorithm that reduces the number of comparison operations and, consequently, the execution time needed to encode an image as compared to the SPIHT algorithm. The threshold of each independent subband is calculated after applying the discrete wavelet transform to the image.
