run.sh compares output of cpu files instead of gpu files with reference files

[Evan Lee]

In run.sh it's checking the output of the cpu with the reference files

run_cmd_with_check diff out.pgm ../reference/out.pgm >> LOG 2>& 1
run_cmd_with_check diff out_yuv.ppm ../reference/out_yuv.ppm >> LOG 2>& 1
run_cmd_with_check diff out_hsl.ppm ../reference/out_hsl.ppm >> LOG 2>& 1

Shouldn't it be

run_cmd_with_check diff gpu_out_grayscale.pgm ../reference/out.pgm >> LOG 2>& 1
run_cmd_with_check diff gpu_out_yuv.ppm ../reference/out_yuv.ppm >> LOG 2>& 1
run_cmd_with_check diff gpu_out_hsl.ppm ../reference/out_hsl.ppm >> LOG 2>& 1

Yea this makes sense. I changed my run.sh file to this and it seems my tests are failing now, but only HSL and YUV. I followed the same steps as the algorithm with conversion and such and the output image seems almost identical, so I'm wondering if its because of how GPU handle floating point differently than CPU?

Thanks; shell scripts and sample images have been updated.

You can obtain both the CPU and GPU generated images from same folder on the website.
