One Shoulder Lean

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 3 121 6 95.04% 1.28 0.43
Compression 2 121 12 90.08% 0.44 0.12

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.


The time required for the algorithm to obtain a selection of N keyframes.
