Left Shimmy

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 3 83 4 95.18% 37.98 19.25
Compression 2 83 8 90.36% 10.52 3.22
Compression 1 83 17 79.52% 2.83 0.60
Original 83 83 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.
