4-Dimensional deformation part model for pose estimation using Kalman
  filter constraints
Enrique Martinez-Berti Antonio-Jose Sanchez-Salmeron Carlos Ricolfe-Viala
The main goal of this article is to analyze the effect on pose estimation
accuracy when using a Kalman filter added to 4-dimensional deformation part
model partial solutions. The experiments run with two data sets showing that
this method improves pose estimation accuracy compared with state-of-the-art
methods and that a Kalman filter helps to increase this accuracy.
