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 lettuce plants from surrounding weeds and vegetation.
- Small lettuce plants at early growth stages were difficult to detect.
- Closely positioned and partially overlapping plants required careful placement.
- Plant sizes and growth stages varied widely across the dataset.
- Complex agricultural backgrounds contained soil, weeds and other crops.
- Varying lighting conditions and shadows affected plant visibility.
- Keeping bounding boxes tight and accurate around individual plants demanded sustained attention.

Bounding boxes around individual almond trees in top-down drone imagery, where shadows and neighbouring vegetation mimicked real trees.
Apple Detection
Bounding boxes around individual apples on tree branches, where dense leaves and occlusion hid much of each fruit.
