title: Conversion of 2D image to 3D image
body: <p>i am going to develope a system which will take a 2D still image as a input &amp; 3D image as a output.
  So the steps are:
  1. creating a depth map from 2D image
  2. creating 3D image from depth map and original image.
  Can anybody suggest me the algorithms to generate the depth map of 2D image?</p>
