+## Workshops and Challenges
+1. We organized the [AIM 2025 Rip Current Segmentation (RipSeg) Challenge](https://www.codabench.org/competitions/9109/) challenge at AIM workshop in conjuction with [ICCV2025](https://iccv.thecvf.com/). See the [AIM 2025 Rip Current Segmentation (RipSeg) Challenge Report](https://arxiv.org/abs/2508.13401) on arXiv, which will be published in the ICCVW2025 Proceedings.
+1. Another challenge coming soon, stay tuned.
 
 ## Known Limitations
 1. Some of the videos have been annotated with Roboflow. By default, Roboflow sorts files by "Newest". This, however, is rather random when uploading files in bulk. We realised this at some point and sorted the files by filename, leading to annotations in the frame order. However, for the videos annotated with "Newest", the annotations can be quite jittery when overlaied in a video. This does not affect the quantitative results in any observable way and is strictly a visual issue. 
 1. Video sampling rate varies greatly, depending on video duration, movement and annotator disponibility at the specific time. Frames are usually numbered in such a way that they match the exact frame from the video (e.g. RipVIS-015_00005.jpg is the 6th frame from RipVIS-015 video). However, several annotations contain the frames in order, with frame number not matching the actual frame from the video. The actual frame can still be reasonably accurately found by calculating the sampling rate, the total number of frames and the total number of annotated frames. We will fix this in a future patch.

-1. Somes sampled and annotated frames were removed due to invalid annotation format (an error most likely created in transitioning from video to frames to Roboflow and back). While we mitigated this, it is still the case that a a small number of annotated frames might be missing in the published version.
