Temporal resolution vs. visual saliency in videos: Analysis of gaze patterns and evaluation of saliency models
作者：
Highlights：
• First, we study effects of video frame rate on visual attention via eye-tracking.
• We observe significant influence of video frame rate on average gaze patterns.
• We observe significant influence of frame rate on subject-wise changes in eye-paths.
• Second, visual saliency models are evaluated for videos with different frame rates.
• Trade-off of saliency prediction accuracy and consistency over frame rates is shown.
