The images are acquired in time from 3 h to 72 h after inoculation, the errors related to the reference image taken just after inoculation. \(\Delta q_{rms}\)—RMS displacement of control points in an image without alignment, \(\Delta r_{rms}\)—RMS displacement of the control points after affine type registration, \(\delta_{rms}\)—percentage displacement error after affine registration
