Extraction of the least significant bit of a pixel

I want to extract the least significant bit (LSB) of each pixel in an image. I want to know what is the value of LSB in each pixel, whether it is 1 or 0. How do I do this in MATLAB?

You can use the bitget function and specify the bit position of 1, denoting the LSB of each pixel. Assuming your image is stored in A, simply do:

B = bitget(A, 1);

B will be the same size as A which tells you the LSB of each pixel in the image.
