A Python script evaluating PSNR metric of two YUV420 frames
A script evaluating PSNR metric of two YUV420 frames.
usage: psnr.py filename1.yuv filename2.yuv frame_width frame_height
Alternatively if filename1 contains width and height in the form file-1200x1600.yuv,
the script will extract width and height of a frame from the filename. Then usage even simplier:
psnr.py filename1-1200x1600.yuv filename2.yuv
usage: psnr.py filename1.yuv filename2.yuv frame_width frame_height
