Algorithm and VLSI Architecture Design of Low-Power SPIHT Decoder for mHealth Applications
IEEE Transactions on Biomedical Circuits and Systems, 2018A real-time cost and power-efficient (CPE) set partitioning in hierarchical trees (SPIHT) decoder design with low hardware complexity and low-power dissipation is introduced in one-dimension (1-D) wavelet-based quality-assured electrocardiograph (ECG ...

Vector Quantization in SPIHT Image Codec
2006The image coding algorithm “Set Partitioning in Hierarchical Trees (SPIHT)” introduced by Said and Pearlman achieved an excellent rate-distortion performance by an efficient ordering of wavelet coefficients into subsets and bit plane quantization of significant coefficients.

Generalization of SPIHT: Set Partition Coding System
IEEE Transactions on Image Processing, 2016This paper constructs a set partition coding system (SPACS) to combine the advantages of different types of set partition coding algorithms. General tree (GT) is an important conception introduced in this paper, which can represent tree set and square set simultaneously.

2018 International Conference on Advancement in Electrical and Electronic Engineering (ICAEEE), 2018
This paper mainly discusses about digital image (MRI image) compression using different parameters. A database of image contains huge number of images and therefor file size may be in GB or Large MB type.

Shadow SPIHT with Discarded Lists
2015 1st International Conference on Next Generation Computing Technologies (NGCT), 2015Various methods and algorithms have been designed and implemented for the purpose of image compression. These techniques are highly valuable as the present day networking system is widening day by day and there is an emerging requirement to shrink the size of images for their quick and efficient transfer.

Iris recognition with image compression using SPIHT
Proceedings of the International Conference and Workshop on Emerging Trends in Technology, 2010Iris recognition is used to identify people. A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Commercial iris recognition systems are used, to allow access to secure areas, and for secure access to computer networks.

Modified SPIHT wavelet compression for ECG signal
Journal of Medical Engineering & Technology, 2007This paper presents a modified version of Set Partitioning In Hierarchical Trees (SPIHT) wavelet compression method, which has been developed for ECG signal compression. Two more steps in the existing technique have been added to achieve higher compression ratio (CR) and lower percentage rms difference (PRD).

A new improvement of SPIHT progressive image transmission
Fifth International Symposium on Multimedia Software Engineering, 2003. Proceedings., 2003To generate optimal transmission quality for images, we present a new technique to improve the progressive image transmission (PIT) of SPIHT. The original approach about the progressive image transmission is that SPIHT regards the bit streams acquired from every truncation as a transmission in every phase; in every truncation, SPIHT not only refine the
