  1. 2D to 3D ConversionUsing 3D DatabaseFor Football Scenes KianaCalagari Final Project of CMPT880 July 2013

  2. 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

  3. Using 3D Database 3D Dataset : ? 2D Query :

  4. How? • 5 Nearest Neighbours Using HOG descriptors

  5. How? • Warping Using SIFT-flow

  6. How? • Initial Depth Map Median of the Candidates

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

  8. Final Result

  9. Results

  10. 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
