i want the intensity color in my binary image because after i get that i want to use threshold adaptive method. because in threshold i want to differentiate the dark intensity and bright. within by use threshold i can get only the image i want...thank you.

Well, sorry but that makes no sense for several reasons. Why don't you just post your binary image, and original color or gray scale image if you have one? Then read this link and tell us what you want to measure, and we'll tell you the best approach.

If you have a binary image, BW, then the intensity image that corresponds is
IntensityImage = double(BW);

A binary image by definition is exactly two intensities. A binary image cannot have grayscale intensity.
What you probably want is to use .* to multiply your binary image by your grayscale image. The result will be a grayscale image that is 0 everywhere the binary image was 0.

You can mask your image to show only the pixels in the binary blob locations but with their original grayscale intensity like this:
outputImage = grayImage; % Initialize
% Now make black in binary image black in the gray scale image.
outputImage(~binaryImage) = 0; % Be sure to use the ~ tilde!
imshow(outputImage, []); % Or don't use [] if you don't want it to scale intensity.
