Visibility of Motion Blur and Strobing Artefacts in Video at 100 Frames per Second

A Study of High Frame Rate Video Formats

“…Previous research has demonstrated that there are a number of clear benefits associated with increased frame rates, including: the visibility of temporal aliasing artefacts being diminished [10,[21][22][23][24][25][26]; a reduction in perceptible motion blur [23][24][25][27][28][29]; increased realism, smoother motion, improved depth perception for both expert [30] and non-expert [31] viewers (especially when tracking using smooth pursuit eye movements); more realistic motion image quality (confirmed using EEG data) [32]; a reduction in viewer stress levels [33] (signified by a lower blinking frequency [34]); an improvement in speed and spatial discrimination, and reading ability [35]; and an increase in perceptual quality [18,36], at least up to 240 fps [29]. The use of higher frame rates also enhances the ability to capture and playback slow-motion videos [37].…”

“…Few (if any) high frame rate (60 fps+) video databases have ever been released [39]. Related work has either considered relatively low frame rates (up to 30 fps [40][41][42]), or the research data has not been published in its entirety (missing subjective evaluations and/or source sequences) [25,[27][28][29][30][31].…”

Perceptually-Aligned Frame Rate Selection Using Spatio-Temporal Features

“…2. Furthermore, due to the fact that a fully open shutter angle was used for the acquisition of the sequences, motion blur artifacts are expected [5], especially in sequences with objects moving relative to the camera, as for example the video sequences cyclist and joggers in Fig. 2.…”

“…High frame rates are important as they improve perceptual video quality and reduce the visibility of motion artefacts (e.g. motion blur, aliasing) [3][4][5][6]. However, increasing the frame rate, significantly raises bandwidth demands and makes the task of video delivery even more challenging for the service providers.…”

A Frame Rate Conversion Method Based on a Virtual Shutter Angle

“…Increasing video frame rates will lead to greater realism, smoother motion, improved depth perception and higher visual quality [1]- [4] through a reduction in the visibility of temporal aliasing artefacts [5]- [10] and motion blur [11], [12]. However moves towards high frame rate formats (60 fps+) will require robust techniques for frame rate conversion -especially when converting to legacy formats e.g.…”
