i am working on wavelet filter for image analysis.

Hello sir. I found the wavelet coefficients using 3rd section of this paper but in 2 dimension https://drive.google.com/?tab=mo&authuser=0#my-drive

Help me to find energy compression ratio

I don't see how that link will work except to give somebody a link to their own google drive.

If you have your wavelet coefficients, then you can use wdencmp to determine the energy compression ratio.

is there any other parameters require before apply this command.. bcoz i am not getting my answer..

what i have with me is a image of size 500*380 and filter coefficient of size 1*124. plz let me know

[Wayne King]

That is a very long wavelet filter, 124 taps. Are you sure that is a wavelet filter? What is the scaling filter? is this an orthogonal, or biorthogonal wavelet?

[tamanna]

this is orthogonal one..

actuly..according to the paer i provide you the link.. i got these filter coeficient..this is a STATISTICALLY MATCHED HIGHPASS WAVELET FILTER
