"WebFor this purpose you should keep the kernel height bigger than your font height. If the kernel fits inside the character, it will be “eaten”. 1x10 is a very small rectangle and this way it’s expected to get inside some letters. I choose 80 in this example because 1x80 is the smallest rectangle that doesn’t fit inside a text character. " - Opencv thinning example
