How to find the stroke width of handwritten image?

Can anyone please help me with the code to find stroke width as mentioned below? "the stroke width is measured on word level to reflect the variation between words. To prevent the over-measurement of the stroke width, the maximum boundary has been set to a value of (WordImageHeight ÷ 4) before scanning. Through the horizontal and vertical scan of the image for the transition distances of foregrounds, the most occurring transition distance becomes the stroke width of the word image." Please help me how to write its code...
