Area of Science:

  • Botany and Plant Science
  • Computer Vision and Image Recognition
  • Developmental Biology

Background:

  • Flower petal arrangements are key indicators of floral development but difficult to identify.
  • Existing image recognition methods require large datasets, which are unavailable for floral studies.
  • Automating petal arrangement analysis is needed for broader accessibility beyond specialists.

Purpose of the Study:

  • To develop an image recognition method for estimating floral organ arrangements (petals and tepals).
  • To overcome the challenge of limited image datasets in machine learning applications for botany.
  • To provide a tool that supports the identification of petal arrangements for developmental studies.

Main Methods:

  • Utilized a fine-tuned YOLO v5 model for flower detection and GrubCut for segmentation.
  • Employed the Harris corner detector for overlap detection and MAML for interior-exterior pattern estimation.
  • Applied circular permutation matching for arrangement estimation, coupled with a user interface for manual correction.

Main Results:

  • Individual components (detection, segmentation, overlap, pattern estimation) showed high accuracy.
  • Integrated system accuracy decreased, highlighting the complexity of combining multiple image processing steps.
  • A manual correction interface significantly improved the final tepal arrangement estimation quality.

Conclusions:

  • The proposed method offers a viable approach to floral organ arrangement estimation with limited data.
  • Integration challenges necessitate user-guided correction for robust and accurate botanical image analysis.
  • This technique can aid in the study of floral morphology and developmental processes.
