# Openear Developmental Status Classification
This dataset provides real-world RGB images of maize ears collected in a field environment at Hongqi Base, Hainan, China, for developmental status classification. Images were captured using a ground-based Raspberry Pi HQ camera system with a Sony IMX477R sensor during the 2025-2026 growing season, offering high-resolution visual data for distinguishing between abnormal and normal developmental stages. The dataset contains 6,435 images across 2 classes: Abnormal_Developement, Normal_Developement.
Images per class:
- Abnormal_Developement: 2,152
- Normal_Developement: 4,283
This dataset is indexed on https://project-agml.github.io/ as part of the AgML python library.
