How do i isolate the vertical lines in an image?

Good day, I am trying to isolate the vertical lines in an image to make the image show only the vertical lines present in the image.

[N/A]

I am fairly new to MATLAB.

You can use the imgradientxy function to find gradients along x and y axis. Since the vertical lines will have gradients along x direction, you can threshold the gradients along x direction to separate the vertical lines. For example, if I is the image

[gx gy]=imgradientxy(I);
VertLines=gx>950 % Choose a proper threshod
figure, imshow(VertLines,[]);
