To withdraw an abstract prior to the meeting, the first author must send an email to firstname.lastname@example.org.
Under exceptional, unavoidable circumstances, the VSS Board of Directors will consider a co-author replacement for a presentation. To request such a special substitution, a clear explanation must be given in writing in advance (send such requests to email@example.com). If an author substitution is approved, the first author must still pay the registration fee.
Abstracts withdrawn or not presented at the meeting will not be published in the proceedings or in the Journal of Vision.
Authors who fail to present their poster or give their talk without withdrawing their abstract may forfeit the right to present the following year.
