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
- Differentiating Black Grass from Rye Grass, since the two can look very similar.
- Creating precise segmentation boundaries in dense field vegetation.
- Overlapping leaves and plants complicated polygon placement.
- Segmenting small and partially visible weeds.
- Distinguishing weeds from crops and surrounding vegetation.
- Keeping polygon boundaries consistent across different field conditions and lighting.
