Region-based methods are currently achieving state-of-the-art performance for monocular 3D object tracking. However, they are still prone to fail in case of partial occlusions and ambiguous colors. We propose a novel region-based method to tackle these problems. The key idea is to derive a pixel-wise weighted region-based cost function using contour constraints.We verify the effectiveness and efficiency of our method on challenging public datasets. Experiments demonstrate that our method outperforms the recent state-of-the-art region-based methods in complex scenarios, especially in the presence of partial occlusions and ambiguous colors.

The general usage of the algorithm is demonstrated in a small example command line application provided in run_on_video.cc. Here the pose of a single 3D model is refined with respect to a given example image. The extension to actual pose tracking and using multiple objects should be straight foward based on this example. Simply replace the example image with the live feed from a camera or a video and add your own 3D models instead.
For the best performance when using your own 3D models, please ensure that each 3D model consists of a maximum of around 4000 - 7000 vertices and is equally sampled across the visible surface. This can be enforced by using a 3D mesh manipulation software such as MeshLab (http://www.meshlab.net/) or OpenFlipper (https://www.openflipper.org/).
