FD²Foremer: Thinking Face Forgery Detection in Midfrequency Geometry Details

Figure 1

Midfrequency geometry details on facial surfaces during face reconstruction. The uniformity of gray scale in green line area is greater than the same area in real images, which indicates that displacement map extracts less geometry details from fake images. And the unnatural concentration of gray scale in red line circles different themselves from the displacement map of real images. (a) Real images and their midfrequency facial geometry details, (b) fake images and their midfrequency facial geometry details.
