Im trying to detect a point inside a line in this image


Im using this command but only detect the area box and the centroid
what could I do

please help

Inside which line? You will need to turn this image into black and white. Make transparency white. If the point is inside the right side closed curve, then the centroid is likely inside it.

Please explain further.

this

is a random point by each connected image

the centroid not help me for my task

because sometimes coincides with hollow of number figure and Ruin my command to detect numbers

try grep "black" and it will find all black points

convert image txt: | grep "black"

Or if you want only the red ones

convert image txt: | grep "red"
