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,[]);
