Good afternoon,
the attached image is what is obtained when i ran this progam.
How do i connect the points and find the angle between them
thank you.
I = imread ('MR.png')
imshow (I)
disp('Click the mouse wherever in the figure; press ENTER when finished.');
mousePointCoords = ginput;
% plot the mouse point coordinates on the figure
plot(mousePointCoords(:,1), mousePointCoords(:,2),'b.','MarkerSize',8);

For points (x1,y1) and (x2,y2) use atan2(y2-y1,x2-x1) to get angle.
Use plot to plot them as a line.
