Motion Icon: Stage 3
 

In Stage 1, I proposed and implemented a framework for creating motion icon; In Stage 2, I improved the framework as follows:
(1) Improve efficiency by reducing dimension in each frame using SVD decomposition.
(2) Improve the pose clustering using an unsupervised clustering algorithm based on Gaussian Mixture model.
(3) Improve camera setting by using the root trajectory instead of the simple major motion axis.
(4) Improve the visual presentation of the motion icon.

The goal of Project 3 is to develop a sophiscated system for creating motion icon by improving the existing framework. 
Specifically, I will improve the framework in the following way:

(1)  Better key frame extraction algorithm through cluster graph analysis and global motion trajectory analysis.
(2)  Better key frame re-position algorithm through cluster graph analysis.
