2D to 3D Conversion Using 3D Database For Football Scenes Kiana Calagari Final Project of CMPT880 July 2013

Why 2D to 3D? 3D-TVs are available, but…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

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

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

Final Result

Results

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
