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
- Distinguishing Johnson grass from visually similar vegetation.
- Dense and complex agricultural backgrounds reduced clarity.
- Partially visible or overlapping plants had to be identified.
- Plants appeared at different sizes and growth stages.
- Consistent boundaries and class labels had to be maintained across images.
