Region-of-interest coding based on set partitioning in hierarchical trees

IEEE Transactions on Circuits and Systems for Video Technology, 2002
In many image coding applications, such as Web browsing, image database and telemedicine, it is useful to reconstruct only a region of interest (ROI) before the rest of the image is reconstructed. An ROI coding functionality is incorporated with the set partitioning in hierarchical trees (SPIHT) algorithm (see Said and Pearlman, IEEE Trans.

A new, fast, and efficient image codec based on set partitioning in hierarchical trees

IEEE Transactions on Circuits and Systems for Video Technology, 1996
Embedded zerotree wavelet (EZW) coding, introduced by Shapiro (see IEEE Trans. Signal Processing, vol.41, no.12, p.3445, 1993), is a very effective and computationally simple technique for image compression. We offer an alternative explanation of the principles of its operation, so that the reasons for its excellent performance can be better understood.

Wavelet compression of ECG signals by the set partitioning in hierarchical trees algorithm

IEEE Transactions on Biomedical Engineering, 2000
A wavelet electrocardiogram (ECG) data codec based on the set partitioning in hierarchical trees (SPIHT) compression algorithm is proposed in this paper. The SPIHT algorithm [1] has achieved notable success in still image coding. We modified the algorithm for the one-dimensional case and applied it to compression of ECG data.

Wavelet Compression of Multichannel ECG Data by Enhanced Set Partitioning in Hierarchical Trees Algorithm

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
The set partitioning in hierarchical trees (SPIHT) algorithm is very effective and computationally simple technique for image and signal compression. Here the author modified the algorithm which provides even better performance than the SPIHT algorithm.

ECG signal compression by predictive coding and Set Partitioning in Hierarchical Trees (SPIHT)

2015 International Conference on Advanced Computer Science and Information Systems (ICACSIS), 2015
In 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), 2012
In 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, 2008
This 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), 2003
This 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.
