If you want 8 bit, just cast it to 8 bit:
image8bit = uint8(originalImage);
If you want a string of binary digits, use dec2bin()
binaryString = dec2bin(170)
Result:
binaryString =
10101010

Once you extract the pixel from image quantize it to (0,256) fixed point representation. Let the pixel be p(i,j) the output should be [p(i,j)/max_image{p(i,j)*256].
