    Area of Science:

    • Computer Vision
    • Plant Science
    • Image Analysis

    Background:

    • Accurate plant leaf segmentation is crucial for phenotyping and growth analysis.
    • Existing methods struggle with segmenting overlapping leaves in 3D datasets.

    Purpose of the Study:

    • To develop an automated method for segmenting individual plant leaves from 3D images.
    • To address the challenge of segmenting overlapping leaves effectively.

    Main Methods:

    • Utilized structure from motion to generate 3D images.
    • Employed a region-growing algorithm to initially segment non-touching leaves based on proximity (distance < 0.2 cm).
    • Projected segmented leaves onto 2D images and applied the watershed algorithm to separate overlapping structures.
