Shape number in image processing
http://turing.iimas.unam.mx/~ernesto/shape.htm Webb23 juni 2024 · The letter ‘B’ therefore has three connected components, or three white spots (two enclosed in the letter and one that borders the image). There is also a ‘B’-shaped hole where the letter is. Therefore, the Euler number is 3–1=2. You think I’d be better at drawing the letter ‘B’ by this point in my life.
