SPIHT image compression on FPGAs

IEEE Transactions on Circuits and Systems for Video Technology, 2005
In this paper, we present an implementation of the image compression routine set partitioning in hierarchical trees (SPIHT) in reconfigurable logic. A discussion on why adaptive logic is required, as opposed to an application specific integrated circuit (ASIC), is provided along with background material on the image compression algorithm.

A simplified SPIHT algorithm

Journal of the Chinese Institute of Engineers, Transactions of the Chinese Institute of Engineers,Series A/Chung-kuo Kung Ch'eng Hsuch K'an, 2008
Based on the SPIHT algorithms, we define two modifications to develop a simpler image coding method. The first concept is obtained from the relationship between the bit-planes and the target bit-rate. The second concept is obtained from the relationship between the initial threshold and the target bit-rate.

Performance improvement of the SPIHT coder

Signal Processing: Image Communication, 2004
Abstract The set partitioning in hierarchical trees (SPIHT) coder is one of the state-of-the-art coders among the wavelet-based image compression coders. For improving the performance of the SPIHT coder, in this paper, we propose a pre-processing method that applies the discrete sine transform or the discrete cosine transform to the wavelet ...

A Block-Based Pass-Parallel SPIHT Algorithm

IEEE Transactions on Circuits and Systems for Video Technology, 2012
Set-partitioning in hierarchical trees (SPIHT) is a widely used compression algorithm for wavelet-transformed images. One of its main drawbacks is a slow processing speed due to its dynamic processing order that depends on the image contents. To overcome this drawback, this paper presents a modified SPIHT algorithm called block-based pass-parallel ...
