I want to close the open contours like the picture :

And I want to close the open contour as shown in the picture and make it a single contour (single shape) . (Different colors in the picture show different contours).

How can I do that?

I've tried the approxPoly , but did not succeed.

Erosion and dilation are your friend here, combined with the convex hull operator. This will allow you to close the small gap at the top of the E, thus returning a contour around the line and not around the object itself. Have a look at the morphological operations tutorials, here and here.
