Sublabel-Accurate Convex Relaxations

Installation

To run the code, first install the convex optimization framework prost following the instructions presented there.

It is required to add some additional proximal and linear operators to prost. To do so, create the file CustomSources.cmake in the directory prost/cmake/ with the following contents:

set(PROST_CUSTOM_SOURCES
  "relative_path_to_sublabel_relax"/cvpr2016/prost/block_dataterm_sublabel.cu
  "relative_path_to_sublabel_relax"/cvpr2016/prost/prox_ind_epi_polyhedral_1d.cu
  "relative_path_to_sublabel_relax"/cvpr2016/prost/prox_ind_epi_conjquad_1d.cu
  "relative_path_to_sublabel_relax"/eccv2016/prost/prox_ind_epi_polyhedral.cu
  
  "relative_path_to_sublabel_relax"/cvpr2016/prost/block_dataterm_sublabel.hpp
  "relative_path_to_sublabel_relax"/cvpr2016/prost/prox_ind_epi_polyhedral_1d.hpp
  "relative_path_to_sublabel_relax"/cvpr2016/prost/prox_ind_epi_conjquad_1d.hpp
  "relative_path_to_sublabel_relax"/eccv2016/prost/prox_ind_epi_polyhedral.hpp
  )
  
set(MATLAB_CUSTOM_SOURCES
  "relative_path_to_sublabel_relax"/cvpr2016/prost/custom.cpp
  "relative_path_to_sublabel_relax"/eccv2016/prost/custom.cpp
  )

Replace "relative_path_to_sublabel_relax" with the relative path to go from the directory prost/cmake to the directory where you cloned this repository into (e.g., ../../sublabel_relax).

After adding this file, recompile prost again, e.g., run in the directory prost/build

cmake ..
make -j16
