# Openear Base Segmentation
This dataset provides real-world RGB imagery of maize crops in field environments, captured at Hongqi Base, Hainan, China. Collected using ground-based platforms with a Raspberry Pi HQ camera during the 2025-2026 growing season, it supports semantic segmentation tasks for agricultural phenotyping in maize fields. The dataset contains raw and augmented versions.
The raw split contains 919 images with pixel-level mask annotations.
The augmented split contains 3,859 images with pixel-level mask annotations.
This dataset is indexed on https://project-agml.github.io/ as part of the AgML python library.
The original train/test/val split has been preserved in the `split` column.
