Fully spatial and SNR scalable, SPIHT-based image coding for transmission over heterogenous networks, Journal of Telecommunications and Information Technology, 2003, nr 2

, 2003
This paper presents a fully scalable image coding scheme based on the set partitioning in hierarchical trees (SPIHT) algorithm. The proposed algorithm, called fully scalable SPIHT (FS-SPIHT), adds the spatial scalability feature to the SPIHT algorithm ...

Improvements to SPIHT for lossy image coding

We propose five measures to improve the SPIHT (Set Partitioning In Hierarchical Trees) algorithm for lossy image coding. First, a new type of tree with virtual root is introduced to hold more wavelet coefficients. Second, an extra matrix is used to speed

TECHNICAL REPORT 1 SPIHT-based Coding of the Shape and Texture of Arbitrarily-Shaped Visual Objects

, 2008
A new scheme for coding both the shape and texture of arbitrarily shaped visual objects is presented. Based on Set Partitioning on Hierarchical Trees (SPIHT), the proposed Shape and Texture SPIHT (ST-SPIHT) employs a novel implementation of the shape ...

Design and Implementation of a Modified SPIHT Algorithm for Image Compression

, 2007
Among all algorithms based on wavelet transform and zerotree quantization, Said and Pearlman's set partitioning in hierarchical trees (SPIHT) algorithm is well known for its simplicity and efficiency.
