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. $\mathrm{\Delta }{q}_{\mathit{rms}}$—RMS displacement of control points in an image without alignment, $\mathrm{\Delta }{r}_{\mathit{rms}}$—RMS displacement of the control points after affine type registration, ${\delta }_{\mathit{rms}}$—percentage displacement error after affine registration
