MaCVi @ WACV 2027
Tuesday, January 5, 2027, afternoon (Orlando local time), per WACV’s draft schedule. Exact times and room to be confirmed.
Competition submissions closed. The deadline was October 27, 2026, 23:59 AoE. Organisers are validating submissions and analysing results; final standings follow those checks.
Check the individual challenge pages for next steps and instructions: Maritime Visual Odometry, EURS and Diver3D.
Our three challenges cover underwater and surface-based maritime perception. Datasets, evaluation protocols and leaderboards remain available for reference. Updates and track-specific instructions are published on the pages below and in MaCVi Discord.
Competition submissions are closed. Validation and results analysis are underway. Results dates are targets subject to organiser checks; follow each challenge page for updates. WACV extended the publication deadlines on October 27; the current dates are listed below.

AoE means Anywhere on Earth (UTC−12). The organisers' final metadata handoff is November 7, 2026, noon Pacific Time (21:00 Berlin). The archival camera-ready deadline is November 25, 2026; CPS will contact accepted authors with submission instructions. These publication extensions do not reopen competition submissions. See the paper publication schedule for details.
Estimate a boat-mounted camera's trajectory from RGB or thermal video, calibration and frame timestamps. The full development dataset is available: 92 RGB and thermal clips, with a public starter for local inference and evaluation. Validation and next steps.
Detect divers as full 9-DoF oriented boxes — centre, extents and a complete SO(3) rotation — from sparse 3D sonar point clouds. Divers pitch and roll freely, so yaw-only 3D detectors do not apply; ranking is by the Sonar–Diver Detection Score, which weights full-3D orientation error alongside AP. The dataset is available: 36 scenes, 37,010 sonar frames and 34,568 annotated divers, with the official scorer included. Validation and next steps.
Restore degraded underwater images and segment marine life (background/coral/fish/elasmobranch/other). The two tracks are: a public, self-serve Dev-set leaderboard, and an embedded track scored on real Jetson AGX Orin hardware that carries more weight towards final standings.
