Football Hike

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 Maximum Error (mm) Average Error (mm)
Compression 4 197 5 97.46% 73.14 31.53
Compression 3 197 10 94.92% 27.14 6.76
Compression 2 197 20 89.95% 5.62 0.88
Compression 1 197 39 80.20% 1.15 0.20

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.
