29.11.2018 · I am trying to find width of a curve/line segment using openCV in python. The image on the left is the input image. I just need the maximum width. I read that Distance transform can help give the width. I used distance transform and was able to get the image on the right as a result. Now, I am stuck on how do i get the width of the curve from this result image of …

Calculates the distance to the closest zero pixel for each pixel of the source image. The function cv::distanceTransform calculates the approximate or precise distance from every binary image pixel to the nearest zero pixel. For zero image pixels, the distance will obviously be zero.

Nov 30, 2018 · normalizing the distance is a bad idea already, since the max value will always be 1. then, also remember, that the distanceTransform gives you the shortest distance to any zero pixel in the neighbourhood, so it's value is only half of the actual line's width.
