Down sampling problem in Discrete wavelet transform

Hello everyone

I'm newbie in system generator and I ran into a problem, I'm trying to implement discrete wavelet transform (dwt) so i have a 128*256 image, I need to do down sampling to rows; that is I use the first row, omit the second, use the 3rd etc. how can I do that using system generator?

 

Thanks in advance

Re: Down sampling problem in Discrete wavelet transform

There is a down sampling block in the System Generator, FIR Compiler can also implement down sampling.

Re: Down sampling problem in Discrete wavelet transform

Thanks for replay

sir, that block can not help me because it omit only one pixel in a time,

for example if i put setting 5 in down sample 

from every 5 pixel it omit one while i need it to omit first 5 pixel and keep the second 5 pixel and so on 

can you suggest to me another block?
