I got this question by my college director while I was bunking the class.

My doubt is from Gray Scale Vs Binary Imaging topic in division Machine Vision Systems of Engineering Metrology

Answer 1

Right answer is (b) Distance transform

The explanation is: An important characteristic of a binary image is the distance transform. Distance transform gives the distance of every set pixel from the nearest unset pixel. The distance transform can be calculated efficiently.
