I have converted a m X n X 3 image(no color map) to binary, worked on binary and now want to convert the resultant image back to gray scale. i tried changing the logical image to uint8, the result is not as expected. Is there any way to obtain the final image in gray with the same gray scale intensities.
Thanking you in advance.

image(Your_Logical_Image);
colormap(gray(2));
or
gray_Image = uint8(255*Your_Logical_Image);
image(gray_Image);
colormap(gray(256));
