MATLAB: Search for line passing through a point in edge image

Question

Hi all

I have an color image and I converted it to gray image then I do edge detection using 'canny'. The edge image contains horizontal, vertical and inclined lines. For specific pixel (xp,yp) in the edge image, I want to search for a vertical line that pass through this point.

Can anyone help me to find to a method to search or detect a vertical line passing in this point. Your help is highly appreciated.

I started with:

I=imread('image.jpg');

G=rgb2gray(I);

B=edge(G,'canny');
