My algorithm generates a blur map from the input depth map and the user's depth(s) of interest. The blur map is then used to perform depth-based selective blurring of the input image using a Gaussian kernel, resulting in an output image with image regions lying in depth(s) of user's non-interest blurred (degree of blurring is controlled by a input parameter), thus effectively altering the depth of field of the input image.
This submission, used in conjunction with my stereo depth map generator available at:

may be helpful especially for amateur / casual photographers using entry-level cameras with limited capabilities for altering the depth of field during shooting. A typical use case is portrait photography.
A similar project done by GOOGLE, although their depth estimation methodology is different:
