Moving object segmentation for jittery videos, by clustering of stabilized latent trajectories

作者:

Highlights:

• Closed-form solution based optimization to stabilize jerky videos, using OTDM feature matrix

• Accurate tracking using pLSA for matrix factorization

• Ground truth for 16 real-world jerky videos as a new benchmark, for performance evaluation

• Jitter model using homography matrix, to corrupt stable videos with desired levels of jitter

• Superior performance of stabilized tracking on real-world and synthetic jitter patterns
