Dear all,

I need to detect two lines in the picture with left line can't be checked by eyes sometimes. The picture can be got from here (sorry I can only put a link at here since I can't attach files):

I have two questions:
1) the interested part is inside the ellipse, how can I detect this area and pick out that part of image (the rectangle area)?
2) how to detect the location of left line?
