3D-SPIHT

20 Jul 2006 (Updated 20 Jul 2006)

The 3D Set Partitioning In Hierarchical Trees Matlab Code

File Information
Description	These functions implement the 3D SPIHT algorithm, used for the compression of 3d wavelet coefficients. Such 3d wavelet coefficients are produced during the coding of video sequences.
Acknowledgements	The author wishes to acknowledge the following in the creation of this submission: SPIHT
MATLAB release	MATLAB 6.5.1 (R13SP1)

21 Aug 2006	li hai	We can learn more conveniently form communication ,thank you for your code
27 Mar 2007	Mac D	The creator or this code has completely misunderstood the concepts of 3-D SPIHT. No temporal wavelet decomposition is made, for example...
14 Apr 2007	Dionysios Athanasopoulos	Mr Mac D, the role of the 3d SPIHT algorithm is the coding of the wavelet coefficients! The temporal decomposition as well as the spatial is implemented before and independently of the 3d spiht algorithm. The role of the m-file presented is to code the wavelet coefficients and not to implement a video coding system.

17 May 2007	Silik Salonik	The creator of this code does not understand what is the meaning of 3D analysis ... The code he provides has nothing to do with 3D-SPIHT ...
24 May 2007	Gary Cao	The 3D spiht implementation itself is very good. But if the author also implements the temporal wavelet decorrelation first, the work will be much better.
09 Mar 2012	gecece'08@fecebook.com	i didn't under stand which file have to be first excuted plz give the file exceted first,input video bcoz i did nt get any videos in the format of cif.very important to me plz send immediately if possible mail input video to ravi08402@gmail.com
