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 tassels from surrounding grass and vegetation.
- Small or partially visible tassels were easy to overlook.
- Overlapping plants and dense field vegetation complicated box placement.
- Dried leaves proved difficult to separate from other plant material.
- Lighting and field conditions varied considerably between images.
- Objects differed widely in size and orientation, making consistent boxes harder to maintain.
