I am having 4096 blocks ,in which one block is having 64 coefficients ?I need to pass it to a bit plane encoder .My input image is of 8-bit.I dont know how to process this in matlab.Please help me in this regard.

Are you trying to figure out how to break up your image into 4096 blocks? Is each block to be a fixed size?

I have made the image into blocks.ya each block is 64*64.Next procedure is i need to give it to a bit plane encoder.Input image is 8 bit.

Okay, so what is the step you feel you are missing?

I need to decompose the image into bit planes and to do further processing.Its a 8 bit image need to decompose into 8 bit planes,but doesent know how to arrange this blocks in the bit plane structure.

If you are looking to convert a numeric image into binary, then there are arithmetic methods, or you can use dec2bin()

You can use dec2bin() to decompose into bit planes. Or you can use bitget(TheArray, K) where K is 1 to 8.

my actual doubt is can i fix this blocks in the bit plane structure.is it possible to arrange 4096 blocks in a 8 bit plane structure.One block is of 64 coeficients.i/p size of the image is of 512*512

blockbits{BlockNumber} = {BitPlane1, BitPlane2, BitPlane3, BitPlane4, BitPlane5, BitPlane6, BitPlane7, BitPlane8};
