a–p Each sample frame (131st) corresponding to each dot on the x-axis in Fig. 4. These figures show sample frames (131st frames) and their scores from 66 subjects of all the videos evaluated in Fig. 4. Figure 5 presents the sample frames of different videos in the order of increasing MOS that is the subjective score, corresponding to the order of dots in terms of x-axis in Fig. 4. Accordingly, we like to claim that the STVSM which shows the most similar trend to increasing MOS appropriately captures the human eye’s perception for the encrypted videos
