EPPM

Code by Linchao Bao ([email protected])

About

EPPM is an implementation of the optical flow algorithm presented in the paper "Fast Edge-Preserving PatchMatch for Large Displacement Optical Flow" in CVPR 2014.

The source code is different from the original paper in the following ways:

1. The self-similarity propagation scheme proposed in the paper is not used in this implementation. Instead, the implementation uses pixel skipping scheme to reduce patch matching computation.

2. The parameter setting are not the same as that for benchmarking in the paper.

Compiling

The code relies on NVIDIA CUDA (version > 5.0) and only works on NVIDIA GPUs. To compile the code, run the following command:

mkdir build
cd build
cmake ..
make
