Dual-Tree Complex Wavelet Transform-Based Direction Correlation for Face Forgery Detection

<div>Exploring the effectiveness of different frequencies. (a) The original image is transformed by FFT, and we retain and reconstruct frequencies within the circle of radius (<i>r</i>). (b) The accuracy variation when using different frequency components during training.</div>
