Building and Running

Linux

Move to the linux build folder and compile using the makefile. Specifically, from the project root, execute the following commands:

cd build/linux
make
export LD_LIBRARY_PATH=../../opencv/lib:../../matio/lib

Following command line options are available while running:

Option	Description	Default Value
--blockx -x	CUDA kernel block's x dimension	256
--blockx -x	CUDA kernel block's y dimension	4
-d --dsloc	Path to dataset as mat file or folder containing images (depth images must be 16bit)
-device --g	CUDA device to run the application on	0
-dstype --t	Dataset type, can be as matlab for MAT file input or images for images as input,with depth images having bitdepth 16	images

Example commands

When using MATLAB mat files as the input dataset, from the PROJECT_ROOT/build/linux folder, run the command

./bin/SRmeetsPS-CUDA --dstype="matlab" --dsloc="../../dataset/Matlab/mitten_sf2.mat"

When using image files as input, run

./bin/SRmeetsPS-CUDA --dstype="images" --dsloc="../../dataset/Images/Mitten"

Windows

A Visual Studio 2014 solution project can be found in PROJECT_ROOT\build\windows. Unlike the linux project, the dependent libraries are not checked in the repository, and requires OpenCV 3.3 and matio 1.5.10 binaries to build and run.
