Improvement of SPIHT Algorithm
2012 Second International Conference on Intelligent System Design and Engineering Application, 2012In order to enhance the working efficiency of SPIHT algorithm, to reduce its complexity, to implement it easily in the software and hardware, an improvement to the original SPIHT algorithm has been made through adjusting sorting process of wavelet coefficients, substituting for the original chain table structure with one dimensional array, changing ...

Proceedings of IEEE TENCON '98. IEEE Region 10 International Conference on Global Connectivity in Energy, Computer, Communication and Control (Cat. No.98CH36229), 2002
We propose a new video coding scheme based on discrete wavelet transform (DWT), as it provides a better way to address scalability functionalities, than MPEG-2. To code wavelet coefficients efficiently, we use set partitioning in hierarchical trees (SPIHT) and adaptive arithmetic coding algorithms.

SPIHT Algorithm Combined with Huffman Encoding
2010 Third International Symposium on Intelligent Information Technology and Security Informatics, 2010SPIHT is computationally very fast and among the best image compression algorithms known today. According to statistic analysis of the output binary stream of SPIHT encoding, propose a simple and effective method combined with Huffman encode for further compression.

SPIHT image compression without lists
2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002A variant of the SPIHT image compression algorithm called no list SPIHT (NLS) is presented. NLS operates without linked lists and is suitable for a fast, simple hardware implementation. NLS has a fixed predetermined memory requirement about 50% larger than that needed for the image alone.

Robust image hashing based on SPIHT
ITRE 2005. 3rd International Conference on Information Technology: Research and Education, 2005., 2005Media hashing is an important resolving skill of copyright infringement. In this paper, a novel robust image hashing scheme is proposed. The set partitioning in hierarchical trees (SPIHT) algorithm, widely employed in image compression, is used to extract the identification information of images.

Joint SPIHT compression and selective encryption
Applied Soft Computing, 2014Abstract JCSE-SPIHT, an algorithm of joint compression and selective encryption based on set partitioning in hierarchical trees (SPIHT), is proposed to achieve image encryption and compression simultaneously. It can protect SPIHT compressed images by only fast scrambling a tiny portion of crucial data during the coding process while keeping all the ...

FPGA implementation of a reconfigurable SPIHT coprocessor
Seventh International Symposium on Signal Processing and Its Applications, 2003. Proceedings., 2003Third generation mobile communication standards is soon enable an ubiquitous fruition of audio-visual services. Beyond these attractive motivations, some critical factors are hidden: the design of wireless terminals has to deal with limited power budgets and reduced resources availability.
