I have a image such as below which has horizontal and vertical lines in the field of view. I want to segment the vertical line adjacent to the dark area such as in red below and vertical line in the intersection of the horizontal line(as seen in black).The full image has many such structiures. I want to stack all similar segmented structures within the fov (Average measuremnet of red and black) and display.I also want to measure the average x and y as shown below if the red line concaves at the max conving location in y.

I=im2double(im2gray(imread('image.png')));
BW=imbinarize(I);
D=bwareaopen(abs(gradient(I))>0.06,20);
D=imclose(D,strel('disk',5));
black=(median(BW,2)>0);
red=~black;
L=D.*red+2*D.*black;
imshow(labeloverlay(I,L,Colormap=[1,0,0;0,0,0]));
