基于小波变换的图像压缩算法SPIHT算法 - CSDN博客
网页2022年5月25日 · SPIHT 算法编码（set partitioning in hierarchical trees ）即 多级树集合分裂编码。. SPIHT 算法的主要思想是利用给定的阈值与小波系数集合中的每个系数进行比较，如果值大于阈值，则输出一个二进制的数字作为该系数重要性的标志；这个二进制的标志位就是 …
SPIHT Description
网页SPIHT codes the individual bits of the image wavelet transform coefficients following a bit-plane sequence. Thus, it is capable of recovering the image perfectly (every single bit of it) by coding all bits of the transform.
Set partitioning in hierarchical trees - Wikipedia
网页Set partitioning in hierarchical trees (SPIHT) [1] is an image compression algorithm that exploits the inherent similarities across the subbands in a wavelet decomposition of an image. The algorithm was developed by Brazilian engineer Amir Said with William A. Pearlman in 1996. [1]
Modified SPIHT algorithm for wavelet packet image coding
网页SPIHT is a very efficient image compression algorithm that is based on the idea of coding groups of wavelet coefficients as zerotrees. This method is well suited for the dyadic wavelet transform, where child-parent relations are easily established.
SPIHT Image Compression - ScienceDirect
网页2008年1月1日 · This chapter describes the process of mapping the image compression algorithm SPIHT onto reconfigurable logic architecture. It provides a discussion of why adaptive logic is required, as opposed to an ASIC, along with background material on SPIHT and analyzes and evaluates several discrete wavelet transform hardware architectures.
GitHub - theAdamColton/spiht: Python bindings for fast image ...
网页SPIHT is an algorithm originally concieved for image compression. It uses the fact that when a natural image is transformed into its DWT coefficients, the coefficients are highly correlated in a organized hierarchical ordering.
Scalable image compression algorithms with small and fixed
网页2023年5月26日 · The SPIHT image compression algorithm is characterized by low computational complexity, good performance, and the production of a quality scalable bitstream that can be decoded at several bit-rates with image quality enhancement as more bits are received.
An improved SPIHT algorithm for lossless image coding
网页2009年3月1日 · In this paper, we propose a new wavelet-based lossless image coder that is based on a state-of-the-art algorithm, namely SPIHT (set partitioning in hierarchical trees). An algorithmic modification is introduced in order to increase its efficiency.
