Benchmarking of algorithms

Benchmarking of similarity metrics algorithms -

When images are same i.e. image1 and image2 are having exactly same values

./metric --image1 test_images/lena.bmp --image2 test_images/lena.bmp --algorithm all --colorspace 1

MSE : 0 , 0 , 0

PSNR : inf , inf , inf

SSIM : 1 , 1 , 1

MSSSIM : 1 , 1 , 1

IQI : 1 , 1 , 1

./metric --image1 test_images/lena.bmp --image2 test_images/lena.bmp --algorithm all --colorspace 1 --opencl

MSE_openCl : 0 , 0 , 0

PSNR_openCl : inf , inf , inf

SSIM_opencl : 1 , 1 , 1

IQI_opencl : 1 , 1 , 1

When images are different i.e. image1 and image2 are having different values

./metric --image1 test_images/lena.bmp --image2 test_images/lena_blur.bmp --algorithm all --colorspace 1
