A diverse image and biomass dataset collected in an outdoor agricultural setting — dense populations of grass and clover mixtures with heavy occlusions and occurrences of weeds.
GSD 4–8 px per mm
Unlabeled 31,600 images
CVPR W 2019
This dataset is a re-hosting of the GrassClover dataset, originally co-created by Søren Skovsen and hosted by Aarhus University at https://vision.eng.au.dk/grass-clover-dataset (archived version). We thank Department of Electrical and Computer Engineering, Aarhus University for their foundational contribution to this data.
The GrassClover dataset is a diverse image and biomass dataset collected in an outdoor agricultural setting. The images contain dense populations of grass and clover mixtures with heavy occlusions and occurrences of weeds.
The dataset is collected with three different acquisition systems with ground sampling distances of 4–8 pixel per mm. The observed mixed crops vary both in setting (field vs plot trial), seed compositions, yield, years since establishment and time of the season.
Synthetic training images with pixel-wise hierarchical and instance labels are provided for supervised training. An overview of the synthetic labels classes and hierarchy is shown in the figure.
31600 unlabeled images are additionally provided for pre-training, semi-supervised training or unsupervised training.
Two challenges are initiated with the dataset: Semantic segmentation and prediction of the biomass compositions. The challenges are open to the public and available at: competitions.codalab.org/competitions/21122.
We hope the dataset will support research and researchers in the cross domain of agriculture and computer vision. For more information about the dataset please see the dataset description paper.
For inquiries, feedback or collaboration, please contact Søren Skovsen.
