need yo

[hu wei]

good

[Matthew Teow]

Well done

[jin yuan]

i wanna somebody could tell me where to get adaptive binary arithmetic coding code,and thanx very much.

[quer zhu]

nice

[Raghad Al_Assadi]

please,how can i do if wavelet packet transform?
send me any answer at my e-mail.

[Dini Franc]

[avinash bp]

can u plz send me the c or c++ code for speck algorithm...thnk you...
my alternate email id is [e-mail]

[woshidada woshidada]

thank you !It's my need;

[raj kumar]

very good

[raj kumar]

excellent help you are providing to the people

[srinivasarao ronanki]

Its nice to interact as well as helping for all,those who are having problems in coding

[Soman KP]

Excellent tool for researchers and students to play with and understand the concepts

[Sundaram RMD]

Its an excellent package. I had some problems in implementing the idea, which got cleared after going through. Hats off to the programmer.

[Omar Sharif]

Excellent....pray for me as i can be like u....

[Sidharth Modi]

Best code see on this Site

[Gabriel Peyré]

Amazing toolbox!
Great implementation, great results. The different parts of the process are nicely splited.

[M Khan]

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

[rings kanchi]

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

[Humberto Ochoa]

Very good, thank you for this program

[NAVEEN RATHEE]

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.

[Grigorios Tsagkatakis]

Good work

[nithin nagaraj]

Very well written code and very useful. Thanks much.

[prasad prasad]

 

[Nidhi Kulkarni]

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 !!

[hbbpapn omo]

thanks

[Yi ZOU]

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.

[shital khalane]

Your code is very helpful for me.but i want explanation for each & every line so that i can understand coding. can u help me?

[OLIVIERO oli]

good morning
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

[falgun thakkar]

given code is very good, but i want arithmatic code for image compression

[xiao –]

this program has som errors in its psnr,if you want provided with the right one ,plesae contact with me [e-mail]
