Thinking in Frequency: Face Forgery Detection by Mining Frequency-aware Clues
European Conference on Computer Vision, 2020As realistic facial manipulation technologies have achieved remarkable progress, social concerns about potential malicious abuse of these technologies bring out an emerging research topic of face forgery detection.

The normal frequencies of oscillation of a fluid inside certain containers are calculated by expressing the velocity potential as a linear combination of harmonic functions each of which satisfies the free-surface boundary condition. The unknown coefficients are then determined by the application of the bottom boundary condition. This is done for three

Frequency selectivity for frequencies below 100 Hz: Comparisons with mid-frequencies
The Journal of the Acoustical Society of America, 2010Auditory filter shapes were derived for signal frequencies (fs) between 50 and 1000 Hz, using the notched-noise method. The masker spectrum level (N0) was 50 dB (re 20 μPa). For fs = 63 and 50 Hz, measurements were also made with N0 = 62 dB for the lower band.
