Quadtree Decomposition on binary Image

I am a color image from which i have got 3-plane i.e. R,G,B. for each plane i divided it into 8 bit planes. Now for each bit plane i need to apply Quadtree Decomposition. Can anyone help please. Or can some one help me to use qtdecomp function for binary image. How to set threshold for the binary image.

Thank you

It would be 0.5, or any value between 0 and 1, non-inclusive.

But how it can be 0.5 as i have only 1 and 0 as my input.

I need to apply Quadtree Decomposition on bit planes not on the image itself.

Yeah, so? You said that you already have the bitplanes: "for each plane i divided it into 8 bit planes", so is there still a problem?

[sumit kumar]

Suppose sir i have a bit plane like [1 1 1 1 1 0 1 0 ; 0 1 0 0 1 1 0 1 ; 1 1 1 1 1 0 1 0 ; 0 1 0 0 1 1 0 1 ;] Now in that case will the threshold 0.5 works as 0.5*0=0 and 0.5*1=0.5. Another thing is do i need to change the code for the block diagram representation code?

Thank You
