Baseball Umpire
The original animation was obtained from Adobe’s Mixamo animation library.
Reconstruction Performance
The 3D viewer presents the original animation (right-most, with orange indicator overhead) along with a series of animations constructed using Salient Poses. See the table below for further information.
| Animation | Total Frames | Keyframes | Compression | Max Joint Error (mm) | Average Joint Error (mm) |
|---|---|---|---|---|---|
| Compression 4 | 158 | 4 | 97.47% | 268.58 | 81.87 |
| Compression 3 | 158 | 8 | 94.94% | 35.08 | 10.87 |
| Compression 2 | 158 | 16 | 89.97% | 6.18 | 1.91 |
| Compression 1 | 158 | 32 | 79.75% | 1.99 | 0.41 |
| Original | 158 | 158 | 00.00% | 0.00 | 0.00 |
Comparisons
Approximation Error: Greedy vs Optimal
A comparison between Salient Poses and a greedy approximation algorithm showing how approximation error reduces as keyframes are added.
Reconstruction Accuracy: SP vs Maya vs PCA
A comparison of how effectively animations can be reconstructed over a range of compression levels using Salient Poses, PCA (over the poses, not the curves), and Maya’s Simplify Curves algorithm.
Runtime
The time required for the algorithm to obtain a selection of N keyframes.
