Introduction

This repository contains the source code for my thesis, which implements and extends CPM for motion estimation and PatchMatch Stereo for stereo matching.

You can obtain a copy of the thesis at the address: https://elib.uni-stuttgart.de/handle/11682/9592

The estimation results for the standard benchmarks are available at: KITTI-2012, KITTI-2015, MPI Sintel and Middlebury.

Usage

It has been tested on macOS and Ubuntu.

To compile the code, you need to install OpenCV and its contribution module opencv_contrib. In addition, your compiler has to support C++11.

1. Download the repository.

2. Build the code

cd ppm
mkdir build
cd build
cmake ..
make -j4

3. It will generate three demo executables

• ppm_cmd for CPM without post processing (motion estimation)
• ppm_cmd_with_epic for CPM with post processing (motion estimation)
• ppm_st_cmd for stereo matching.

Refer to ppm_commandline.cpp, ppm_commandline_with_epic_flow.cpp and ppm_st_cmd.cpp for how to use it.
