Pervasive Artificial Intelligence Research (PAIR) Labs, National Chiao Tung University (NCTU), Taiwan
The Pervasive AI Research (PAIR) Labs, a group of national research labs funded by the Ministry of Science and Technology, Taiwan, is commissioned to achieve academic excellence, nurture local AI talents, build international linkage, and develop pragmatic approaches in the areas of applied AI technologies toward services, products, workflows, and supply chains innovation and optimization. PAIR is constituted of 18 distinguished research institutes in Taiwan to conduct research in various of applied AI areas.

Object detection in the computer vision area has been extensively studied and making tremendous progress in recent years using deep learning methods. However, due to the heavy computation required in most deep learning-based algorithms, it is hard to run these models on embedded systems, which have limited computing capabilities. In addition, the existing open datasets for object detection applied in ADAS applications usually include pedestrian, vehicles, cyclists, and motorcycle riders in western countries, which is not quite similar to the crowded Asian countries like Taiwan with lots of motorcycle riders speeding on city roads, such that the object detection models training by using the existing open datasets cannot be applied in detecting moving objects in Asian countries like Taiwan.
In this competition, we encourage the participants to design object detection models that can be applied in Taiwan’s traffic with lots of fast speeding motorcycles running on city roads along with vehicles and pedestrians. The developed models not only fit for embedded systems but also achieve high accuracy at the same time.
This competition is divided into two stages: qualification and final competition.
Qualification competition: all participants submit their answers online. A score is calculated. The top 15 teams would be qualified to enter the final round of the competition.
Final competition: the final score will be evaluated on MediaTek Dimensity 1000 Series platform for the final score.
The goal is to design a lightweight deep learning model suitable for constrained embedded system design to deal with traffic in Asian countries like Taiwan. We focus on detection accuracy, model size, computational complexity, performance optimization and the deployment on MediaTek’s Dimensity 1000 platform.
With MediaTek’s Dimensity 1000 platform and its heterogeneous computing capabilities such as CPUs, GPUs and APUs (AI processing units) embedded into the system-on-chip products, developers are provided the high performance and power efficiency for building the AI features and applications. Developers can target these specific processing units within the system-on-chip or, they can also let MediaTek NeuroPoint SDK intelligently handle the processing allocation for them.
Given the test image dataset, participants are asked to detect objects belonging to the following four classes {pedestrian, vehicle, scooter, bicycle} in each image, including class, bounding box, and confidence.
According to the points of each team in the final evaluation, we select the highest three teams for regular awards.
Champion: $USD 1,500
1st Runner-up: $USD 1,000
2nd Runner-up: $USD 750
Special Awards
Best accuracy award – award for the highest mAP in the final competition: $USD 200;
Best bicycle detection award – award for the highest AP of bicycle recognition in the final competition: $USD 200;
Best scooter detection award – award for the highest AP of scooter recognition in the final competition: $USD 200;
All the award winners must agree to submit contest paper and attend the ACM ICMR2021 Grand Challenge PAIR Competition Special Session to present their work.

Qualification Competition
The grading rule is based on MSCOCO object detection rule.
The mean Average Precision (mAP) is used to evaluate the result.
Intersection over union (IoU) threshold is set at 0.5.
The resulting average precision (AP) of each class will be calculated and the mean AP (mAP) over all classes is evaluated as the key metric.
Besides, during the qualification competition period, each team has to submit a team composition document, including team name, leader, team members, affiliation, and contact information, etc.
Final Competition
Accuracy of final submission cannot be 5%% lower (include) than their submitted model of qualification.
The summation of Preprocessing & Postprocessing time of final submission cannot be 50%% slower (include) than the inference time of the main model. (evaluated on the host machine)
The team with the highest accuracy will get the full score (40%%) and the team with the lowest one will get zero. The rest teams will get scores directly proportional to the mAP difference.
The team with the smallest model will get the full score (15%%) and the team with the largest one will get zero. The rest teams will get scores directly proportional to the model size difference.
The team with the smallest GOP number per frame will get the full score (15%%) and the team with the largest one will get zero. The rest teams will get scores directly proportional to the GOP value difference.
The team with a single model (w/o Preprocessing & Postprocessing) to complete the detection task in the shortest time will get the full score (30%%) and the team that takes the longest time will get zero score. The rest teams will get scores directly proportional to the execution time difference.
The evaluation procedure will be toward the overall process from reading the private testing dataset in final to completing submission.csv file, including parsing image list, loading images, and any other overhead to conduct the detection through the testing dataset.
