Why 2D to 3D?• 3D-TVs are available, but…
It takes time for enough 3D videos to be produced
Generating 3D content is so time consuming and needs expensive equipment
There is a large library of current 2D videos

How?• 5 Nearest Neighbours Using HOG descriptors

How?• Warping Using SIFT-flow

How?• Initial Depth Map
Median of the Candidates

How?• Cross Bilateral Filtering
Smoothing, While preserving the edges

My New Idea • Instead of estimating the depth itself from the
dataset . . . Estimate its orientation and depth gradients !
Since we’re finding similar images based on gradients
