Abstract :
This study aims to understand how perceived quality of a video varies as the frame rate changes. We find that an inverted falling exponential function can accurately reflect the trend observed from subjective testing. We further explore the relationship between the falling rate and the video content features, such as frame difference, motion, and contrast.
