coarse-to-fine-patchmatch

An implementation of Coarse-to-fine PatchMatch(CPM) Optical Flow

Description

• An implementation of Coarse-to-fine PatchMatch Optical Flow described in [1].
• Re-implementation of original CPM(https://github.com/YinlinHu/CPM) for OpenCV.

References

• [1] Y. Hu, R. Song, and Y. Li. Efficient coarse-to-fine PatchMatch for large displacement optical flow. In CVPR, 2016.

Requirement

• OpenCV
• OpenCV xfeatures2d module (for DAISY Descriptor)

How to build

$ git clone https://github.com/gishi523/coarse-to-fine-patchmatch.git
$ cd coarse-to-fine-patchmatch
$ mkdir build
$ cd build
$ cmake ../
$ make

How to run

./cpm image1 image2

• image1
  • the 1st input image
• image2
  • the 2nd input image

Example

./cpm ./images/MPI-Sintel/frame_0001.png ./images/MPI-Sintel/frame_0002.png
