Openear Projection Segmentation

This dataset provides real-world RGB images of maize ears in a field environment at Hongqi Base, Hainan, China, captured using a ground-based Raspberry Pi HQ camera system. Collected over a period from March 2025 to January 2026, it offers a longitudinal resource for semantic segmentation tasks in agricultural phenotyping under natural field conditions. The dataset contains Augmented and Raw versions. The Augmented split contains 1,048 images with pixel-level mask annotations.

The Raw split contains 248 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.
