i was finding this from a long time i find it here it is in a good form thanks to the Vallabha Hampiholi

[doaa rady]

i need to under stand this algorithm

[doaa rady]

i need the documents of this function algorithm to understand it

[doaa rady]

is this function available for fingerprint compression

[rob thomas]

very good

[abhinit samchin]

hope , this coding will helful in our project,thanking u

[diana rebecca]

the output for 8*8 blocks is not clear...can I know wht is the standard block size used..

[Deema Halabi]

i have lucky for meeting you in this site
thank u.

hi,
i tried using this function for a 4x4 lena image but matlab is showing errors for functions imread and the parameter in_put for the function out_put. could you please let me know how i can best use your function in matlab?

Matlab stops responding with a block_size = 4.

In decoding,exchange "Mu" for "Mi" ,the result is better.
