Your 'reply asap' is counterproductive. Ordering us to help you is more likely to result in you not getting any help.

What's not clear about the error message?

BITAND performs an AND operation on the bits. This is defined for integer types only in a strict sense, but Matlab offers the method for double arrays also, if they have integer values. Exactly as the error message explains.

[EDITED] You can solve this by converting the image to an UINT8 type:

imageD = rand(256, 256);      % Test data
image8 = uint8(image * 255);

Now bitand should work.
