Hi i wonder why white pixels value is 255? This is not intuitively.

2^8 = 256 counting from 0 is 0-> 255 is in total 256, This is ==> a 8 bit memory need for each pixel, this is a commonly stored way of pixels. It could be more or less, but this depend what you want

I understand binary image like an image with two values 0 and x . x can be 1 or offen 255 but you can use what you want for example for threshold it's maxval
~0 == 255 , ~255 == 0 (for 8bit)
~0 == 65535 ;)
But offen for binary image code looks like
So binary image is 0 and something not equal to zero
