Thank you so much for sharing this great code. It's helping me a lot to learn SPIHT. Can anybody please tell me why 'value' is defined as: value = floor(abs(2^(n_max-n+1)*m(LSP(temp,1),LSP(temp,2))));
instead of just taking the values from LSP? Thank you!
Can somebody please share the matlab code for colour image compression using SPHIT algorithm and Isphit Algorithm.My email ID: firstname.lastname@example.orgemail@example.com
Many thanks in advance.
OutSize and image_spiht are never used in fact. Last line assumes silently that dimensions of the image are power of 2 and that there are at least as many columns as rows. Perhaps this would be better:
level = floor( log2( min( [ nRow, nColumn ] ) ) );
Matlab code analyzer complains a lot about variables growing inside the loops. I think that optimizing that could improve performance a lot.
Hello everyone, I have a problem with the SPIHT algorithm, when the images are different from 512x512, someone could help me. thank you very much. My email is firstname.lastname@example.org If you find the solution, thank you very much
given code is very good, but i want arithmatic code for image compression

i want to convert a signal with .dat extention to binary signal .bin
because i want to compression ECG
i can't undestand the code gived..please help
thanx a lot

Your code is very helpful for me. But i found that your root nodes are not in the LL. Am i right? Thank you again.

the code is excellent but i want to access the compressed file and want to know the size of that compressed file in KB/MB as well as in pixels....
can u guide me please...
thanx a lot !!

I am using SPIHT algorithm for imge compression. in C language as specified in the AMIR SAEED IEEE PAPER. i want to go for programming in the MATLAB i am finding problem in C during LINKING and also in MATLAB EXECUTION PLEASE HELP ME OUT.

Very good, thank you for this program

To all: sum2 means the 2-D summation. That is, sum2(X) = sum(sum(X)) for the input 2-D matrix X.

I used the SPIHT coding from your program. It nice. Thank you.
But func_SPIHT_Main.m gives some problems there is call to sum2 but i could not find any method sum2 func_SPIHT_Main.m gives error message. I replace sum2 with sum but it gives some other error.s
