Sunflower, Ragweed & Grass Segmentation

Challenges

• Differentiating ragweed and grass from other weeds and field vegetation.
• Sunflower plants surrounded by dense vegetation were hard to isolate.
• Similar appearance between plant species made classification challenging.
• Overlapping leaves and plants made individual segmentation difficult.
• Thin grass structures required careful polygon placement.
• Partially visible plants needed accurate boundary estimation.
• Different growth stages produced significant variation in plant size and appearance.
• Shadows, lighting conditions and complex agricultural backgrounds affected plant visibility.
• Keeping segmentation boundaries accurate across multiple classes required significant attention to detail.
