Hey there mitesh114 !
Automatically making an actual 3d mesh from only a picture is impossible to do automatically as there isn't enough information to create the 3d model.

If you are looking to do a basrelief mesh out of a photo that is a whole other story. You can use a (white and black) displacement map to form an actual 3d mesh or a normal map for the ilusion of a 3d mesh. All of those are done in most of the major 3d applications like the expensive Autodesk 3ds max/Maya/XSI to the free Blender.
You could create another illusion of a 3d space using an image and Z-Depth image composed of a white and black scale (white representing the closest point and black the farthest). This is used mostly for compositing though.

Hello mitesh114,
/
An automatic 3D representation of an image I believe is very limited in the industry at the moment. If you mean creating a 3D Mesh from an image that is another story. There is many programs out there that you are able to create a 3D mesh from a photo like 3D Studio max, Auto Desk Maya, and other 3D applications.
I think that you are trying to do something like this though but I could be wrong.
