Activity times are based on the Taiwan time zone (GMT+8)
- Open to high school students, university/college students, and professionals nationwide. Teams are not required to include non-citizen members; however, teams that include non-citizens (excluding citizens of the People's Republic of China (PRC)), and not limited to the Indo-Pacific region) are encouraged to apply.
- Teams with a higher proportion of non-citizen members will be given priority in selection. Teams must submit resumes, past notable achievements, and background information of members during registration for the preliminary round. The organizer will review these submissions based on the aforementioned priority principle to determine the final list of participants.
- The competition consists of two stages: the Preliminary Round and the Finals. The list of finalists advancing to the Finals will be announced after the Preliminary Round concludes.
- All team members are required to attend the designated technical workshops for each competition stage in full, including both the Preliminary Round Technical Workshop and the Final Round Technical Workshop (held either on-site or online, as announced by the organizer). Full attendance by all team members is mandatory for each workshop. Teams that fail to ensure the full participation of all members will be disqualified from the competition.
- During the Preliminary Round, the maximum number of daily uploads is 3. The final upload of the day will serve as your score for that day. In the event of identical scores, rankings will be determined based on the submission time; earlier submissions will rank higher.
- Participating teams are strictly prohibited from using multiple accounts, manually labeling test data, attacking the leaderboard system, or using any other unfair methods to manipulate the competition results. Violators will be disqualified from the competition and prize eligibility.
- Participants are allowed to use open-source data augmentation datasets and open-source pre-trained models, provided that all resources used are publicly available under open-source licenses. The sources of these data augmentation datasets and pre-trained models must be explained in a document and submitted along with the results.
- The data, technology, and source code used in the competition entries must be original to the participating team or legally authorized. If any infringement of intellectual property rights is verified by the organizer, the team will be disqualified from the competition and prizes, and the team shall bear all relevant legal responsibilities.
- Finalists or winning teams must submit model weights, source code, execution instructions, and related documentation as requested by the organizer for verification and acceptance. The authorization of the submitted models is limited to academic, public welfare, and official uses by the organizer, and shall not be used for commercial activities.
- Participating teams must achieve an mAP@0.5 of 0.6 or higher in the Preliminary Round to qualify for the Finals. If fewer than 10 teams meet this standard, the Finals may be left unawarded or the format may be adjusted at the organizer's discretion.
- Training and Prediction Strategy: Contestants must exclusively adopt a "post-mapping" strategy. Specifically, models must be trained using the original 34 source categories. The prediction results must only be mapped to the 20 official recognition categories during the final evaluation phase.
- To ensure fairness, regular employees, contract personnel, and individuals assisting in the execution of this competition from the organizing and co-organizing institutions (including the National Academy of Marine Research, DIGITIMES, ITRI, and AWS) are not eligible to register.
- The organizer reserves the right to adjust the competition system, data release methods, evaluation rules, and announcement details.
- Matters not covered herein will be resolved through mutual consultation based on the situation at the time.
- By completing the registration, all participants are deemed to have read and agreed to abide by the competition regulations and all relevant rules.
- In case of any dispute, the organizer reserves the right of final interpretation of the event.
- Please read the Supplementary Provisions for other competition regulations.
- Registration is team-based, with 2 to 5 members per team. Each group should appoint one representative to fill out the team information on the registration website. Each individual may only participate in one team.
- The organizer will send notifications (detailed competition and workshop details, schedules) via email. Please keep an eye on your inbox and ensure that the email address is entered correctly.
- Team composition may only be changed during the registration period (maximum of five members per team). Please contact the International Marine Debris Image AI Recognition Challenge Organizing Team at mdivrc@digitimes.com before the registration deadline. No changes will be accepted after the deadline.

Preliminary Round & Finals
The evaluation metric uses mean Average Precision (mAP)[1] at an Intersection over Union (IoU)[2] threshold of 0.5. A prediction bounding box is considered a True Positive (TP) if its IoU with the ground truth bounding box is greater than 0.5; otherwise, it is a False Positive (FP). Precision is then calculated based on TP and FP counts. The system evaluates the AP score for each object type and then averages the AP values across the 19+1 classes of marine debris objects to obtain the final mAP evaluation value, which determines the ranking. The system uses the COCO API[3] to calculate the mAP values.

Best Lightweight Optimization Award
To encourage teams to develop models that balance practical application, high performance, and
low resource consumption, the "Best Lightweight Optimization Award" has been specially established. This
award utilizes the NetScore metric for comprehensive evaluation. All teams that successfully advance to
the Finals and submit a valid model complying with the regulations will automatically qualify for this
award.
The evaluation formula is defined as：Ω = 20 log₁₀(a² / (√p √m))
•𝑎（Model Accuracy）: Measured as a percentage of mAP. For example, if the mAP is 0.85, then $a = 85$
•𝑝（Model Parameter Count / Size）: Evaluated based on the model size in MB
•𝑚（Computational Complexity）: Evaluated based on GFLOPs
Note: The slots for this award are calculated independently from the top three spots in the Finals (Core Awards). Participating teams are eligible to win both a Core Award and the Best Lightweight Optimization Award simultaneously.
Data Description
- The competition data originates from the existing marine debris image dataset of the National Academy of Marine Research, accumliating over 20,000 images annotated with YOLO bounding boxes. It covers common coastal debris, plastic waste, fishery-related waste, and other anthropogenic debris.
- The original image dataset contains 34 source categories (33+1 classes). Contestants must consolidate these into 20 official recognition categories (19+1 classes).
- The competition scoring is evaluated based on these 19+1 major marine debris targets.
- Detailed category mapping rules are as follows:
- The first 20 categories (ID 0–19) are the main categories.
- Subsequent categories (ID 20–33) are merged into the main categories.(The detailed mapping and consolidation rules are pending official announcement.) The first 20 categories (ID 0–19) are the main categories.
