Poly line in ground truth labeling

Greetings

I am trying to follow this blog for lane detection

https://blogs.mathworks.com/deep-learning/2017/11/17/deep-learning-for-automated-driving-part-2-lane-detection/

but I am stuck in the step of labeling as I can not find any region of interest that is called polyline in ground truth. how could i make it?

thank you in advance

Hey @Nada Selim,

In the blog post Deep Learning for Automated Driving (Part 2) – Lane Detection, the term polyline refers to the Line type label available in the Ground Truth Labeler. For example, a Line label such as LaneDivider can be defined and used to represent a lane by drawing a polyline—essentially a line made up of multiple consecutive points.

More information about the different ROI labels can be found at:
