Extract information from grayscale image

Hi everyone, I need to extract some information from the attached grayscale image. Since this kind of image contains information (multiple lines, shading) I cannot convert to binary image to avoid loss of information. Generally my main objective is to understand the image intensity so that I can identify which one is front or rear dimensrion.
Thank you

Line drawings are ambiguous. You can't tell whether the two upper quadrilaterals are closest to you (so that the "notch" is in the back and you are looking at the underside), or the notch is in the front and you are looking down at the object. A classical line drawing of the 12 sides of a box is similar - you can't tell.
Why do you have to do this anyway? What is the "use case" (to use extreme programmer's lingo)

I'm not sure without researching it. It won't be easy. You can start here: http://en.wikipedia.org/wiki/Hidden_line_removal
You didn't answer my second question about why you need to do this. Do you know?
