A Novel Wavelet-Based Flicker Metric for Variable Refresh-Rate Displays

• Hamid Reza Tohidypour

Description:

We propose a wavelet packet-based flicker metric for variable refresh rate (VRR) displays, addressing limitations of existing metrics. Our method, integrating temporal contrast sensitivity and wavelets, outperforms current approaches by 17.88% in subjective evaluation across luminance and technology, achieving a Pearson correlation of 89.05%.
