Overview

Demonstrates automated detection of wheat spike grains in agricultural settings, suggesting practical applications for yield estimation.

Key Points

The research aims to automate the detection of wheat spike grains to enhance yield estimation accuracy.
Collected 936 images of wheat spike grains and performed data augmentation to create 3700 images.
Divided images into 80% for training, 10% for validation, and 10% for testing.
Selected six deep learning models including YOLOv8n, YOLOv8s, YOLOv8m, YOLOv8l, YOLOv8x, and Faster R-CNN for model comparisons.
YOLOv8n achieved high precision (96.8%), recall (96.8%), mAP50 (98.9%), and mAP50-95 (58.4%) in detecting wheat spike grains.
Other models showed slightly lower precision, with YOLOv8m at 96.7% and Faster R-CNN at 95.7%.
YOLOv8n demonstrated superior performance with fewer parameters and faster processing times, meeting the requirements for accurate counting.
