The 2025 VSS satellite workshop on computational and mathematical models in vision (MODVIS) will be held May 14-15 in St. Pete Beach FL, the two days immediately preceding the main meeting (which now starts Friday morning, instead of the traditional Friday afternoon). The program consists of contributed oral presentations, which are longer and more interactive than a regular VSS talk, and the schedule is designed to provide many opportunities for discussions during coffee breaks and a generous lunch break. The workshop will conclude on Thursday with a keynote lecture given by James Elder (York University). Each presenter may publish a 1-page PDF extended abstract of their presentation, on the Purdue ePubs system. The abstracts from previous workshops can be viewed here <https://www.purdue.edu/conferences/events/modvis/program.php>. The deadline for submissions is March 1st, but authors may revise their abstracts up until publication by Purdue, typically in the week before the workshop. Discounted registration is available until March 31st, with a deeply discounted rate for students and retirees. Registration fees support refreshments and A/V services; it is not necessary to register for VSS or to be a VSS member to attend MODVIS.
