Sparse Approximation for Nonrigid Structure from Motion

Figure 7

3D reconstruction results on the “Stretch” sequence with two methods, respectively. The red dots denote the ground truth coordinates and the blue circles denote the estimation coordinates. The top row is the reconstruction result with sparse approximation and the bottom row is with the DCT trajectory basis method. Both of the results of these two methods are shown with the , , , and frames through different visualizations (better viewed in color).
