Dear colleagues,

We cordially invite you to participate in our MVA2023 Challenge on Small Bird Detection.


Challenge description: The task of this challenge is to detect small birds on images, which is categorized to the Small Object Detection (SOD) problem. Distant-bird detection is an important function for unmanned aerial vehicles (UAVs) such as drones to avoid bird attacks, or drive away harmful birds that destroy fields and rice paddies. Thus, this challenge not only raises academic issues in Computer Vision but also promotes practical technology developments that are expected to be employed in real-world applications. The images in our dataset are captured from drones. In addition to the general difficulties of SOD (e.g., lack of geometrical information for small objects), the annotated birds are of different types (e.g., hawk, crow, and wild bird), and have different parallax, postures, and different degrees of motion blur.


The Challenge consists of two categories "Research Category" and "Development Category to encourage a wide range of participants from academia and industry. Participants must select one of the categories at the time of participation.


Research Category: Participants are expected to not only exhibit the top performance but also propose novel technical contribution(s). Accordingly, each participant of this category is required to submit a technical paper.

Development Category: Participants can focus solely on achieving the top performance. No novel technical contribution is required.

Top-ranking participants in the research category are invited to present their paper at MVA2023 and co-author a summary paper for the Challenge.
