Benchmarking of algorithms

Benchmarking of similarity metrics algorithms -

1. 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 MSSSIM_opencl : 1 , 1 , 1 IQI_opencl : 1 , 1 , 1
