# Deepcob Maize Cob Segmentation

Annotated images from DeepCob, a Mask R-CNN pipeline for maize cob phenotyping built on photographs of native maize landraces from the Peruvian maize genebank. Cobs laid out next to a ruler are outlined with polygons, given here as a mask (background, cob, ruler) and matching boxes. The 1,248 images come from the record's annotated training and validation sets, drawn from the older (ImgOld) and newer (ImgNew) genebank photo series and a separate cross-population set (ImgCross); the genebank population of origin is kept where the record lists it. The dataset contains 1,248 images with 8,919 bounding box annotations across 2 categories.

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.
