BoxBlur

Build:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release .. 
make -j

Usage:

./Release/benchmark --input INPUT --output OUTPUT --ker KER --mode1 MODE1 --mode2 MODE2

1. INPUT - input image (ppm only)
2. OUTPUT - output image (ppm only)
3. ker - integer window size
4. mode1 - first mode to launch (Possible MODE values)
5. mode2 - second mode to launch (Possible MODE values)

It will launch in MODE1 and then MODE2 to compare time.

Possible MODE values:

• cpu_conv - CPU convolution without optimisation.
• cpu_sep - CPU separable convolution.
• cpu_acc - CPU convolution with accumulation optimization.
• cuda_conv - CUDA convolution.
• cuda_sep - CUDA separable convolution

Example:

./Release/benchmark --input ../images/big.PPM --output res.png --ker 20 --mode1 cpu_conv --mode2 cuda_conv

Also ./Release/boxblur_cpu and ./Release/boxblur_cuda are compiled, you can use them to test particular modes.
