ECG signal compression by predictive coding and Set Partitioning in Hierarchical Trees (SPIHT)
2015 International Conference on Advanced Computer Science and Information Systems (ICACSIS), 2015In this paper we present a method for multi-lead ECG signal compression using Predictive Coding combined with Set Partitioning In Hierarchical Trees (SPIHT). We utilize linear prediction between the beats to exploit the high correlation among those beats. This method can optimize the redundancy between adjacent samples and adjacent beats.

An image watermarking approach based on Set Partitioning in Hierarchical Trees(SPIHT)algorithm
2012 International Conference on Informatics, Electronics & Vision (ICIEV), 2012In recent times, digital watermarking has become one of the advanced technologies to protect images from illicit manipulations. A non-blind robust Discrete Wavelet Transform domain watermarking approach for images is introduced in this paper. Based on the parent-child relationship between wavelet coefficients, the Set Partitioning in Hierarchical Trees

3D Color Set Partitioning in Hierarchical Trees
Circuits, Systems & Signal Processing, 2008This paper introduces the 3D color set partitioning in hierarchical trees (3D-CSPIHT) low bit rate embedded video coding scheme. The codec exploits the correlation between temporal and spatial wavelet coefficients and the interdependency between luminance and chrominance components to code color video sequences without the need for explicit bit ...

Video coding with virtual set partitioning in hierarchical tree
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003This paper proposes an efficient wavelet based video coding system using virtual set partitioning in hierarchical trees (VSPIHT). A novel composite spatial orientation tree (SOT) is proposed to extend the use of VSPIHT for color frames and the color VSPIHT (CVSPIHT) based hybrid video coder is proposed.

Using set partitioning in hierarchical trees to authenticate digital images
Signal Processing: Image Communication, 2003In this paper, we present a new image authentication scheme to verify the contents of multi-resolution digital images. The authentication message of a given image is generated based on the set partition in hierarchical trees (SPIHT) encoding. When the original authentication message and the SPIHT decoded message of the image to be authenticated are ...

3D-Memory efficient listless set partitioning in hierarchical trees for hyperspectral image sensors
Journal of Intelligent & Fuzzy Systems, 2023Hyperspectral (HS) images contain rich spatial and spectral information. Due to its large size, it is difficult to store, process, analyze, or transmit the critical information contained in it. The compression of hyperspectral images is inevitable. Many transform based Hyper Spectral Image Compression Algorithms (HSICAs) have been proposed in the past ...

Wyner-Ziv Video Coding Based on Set Partitioning in Hierarchical Tree
2006 International Conference on Image Processing, 2006In this paper, we propose a Wyner-Ziv video coding scheme based on set-partitioning in hierarchical trees (SPIHT) which can utilizing not only the spatial and temporal correlations but also the high-order statistical correlations. Wyner-Ziv theory on source coding with side information is employed as the basic coding principle, which makes the ...

Memory Efficient Set Partitioning in Hierarchical Tree (MESH) for Wavelet Image Compression
IEICE Transactions on Communications, 2012This paper presents a memory efficient version of set partitioning in hierarchical tree (SPIHT). The proposed coder called Memory Efficient SPIHT (MESH) uses a single re-usable list instead of three continuously growing linked lists as in conventional SPIHT.
