Optimize the edge detection

Good evening everyone

to highlight the shape of objects in a scene, I called to edge detection. My concern is how to remove small segments of contours which carries no information in relation to objects.

with bwareaopen(BW, P) I improved a little the result, given where I continue to vary P, I eliminate more segments but I destroy the contour of the object.

Can you help me?

thank you

imopen might be more selective in removing segments based on their size.
