Image-Based Sorghum Head Counting When You Only Look Once
This work addresses crop yield estimation for agriculture, but it is incremental as it applies an existing method with tuning to a specific domain.
The paper tackled the problem of counting sorghum heads from aerial drone images using a parameter-tuned single-shot object detection algorithm, achieving an out-of-sample mean average precision of 0.95.
Modern trends in digital agriculture have seen a shift towards artificial intelligence for crop quality assessment and yield estimation. In this work, we document how a parameter tuned single-shot object detection algorithm can be used to identify and count sorghum head from aerial drone images. Our approach involves a novel exploratory analysis that identified key structural elements of the sorghum images and motivated the selection of parameter-tuned anchor boxes that contributed significantly to performance. These insights led to the development of a deep learning model that outperformed the baseline model and achieved an out-of-sample mean average precision of 0.95.
