How to extract pixel values in 8-bit binary format from an image?

I want the image with pixel values in 8 bit binary value.

Answer 1

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].

Why do we divide it in the end?

Just ignore this answer. It's not correct.
