Sample frames for this project are available under NDA. Write to bilal@wortel.ai and we will share the relevant before and after pairs.
Challenges
- Detecting onion heads in dense agricultural environments.
- Partially visible or occluded onion heads had to be handled carefully.
- Onion heads needed separating from surrounding soil and plant leaves.
- Small onion heads were difficult to annotate accurately.
- Varying onion sizes, shapes, lighting conditions and backgrounds reduced clarity.
- Tight and consistent bounding boxes had to be maintained around each onion head.
