Repository Overview

Welcome to the National Agricultural Image Repository (NAIR), a collection of images designed for computer vision and artificial intelligence research in the field of weed management. The need for effective weed management in agriculture is growing as the demand for food and fiber increase, as incidence of herbicide resistance rises, and as the call for more sustainable methods grows louder. In response, researchers and developers are turning to computer vision algorithms to help automate the detection and identification of weeds in agricultural fields.

This dataset was created to support this research by providing a diverse and large collection of labeled images that represent different types of weeds, cover crops, and crops, grown in different settings and growing conditions. A semi-automatic approach that uses photogrammetry, classical digital image processing, and deep learning has been used to generate multiple type of labels, capturing information about the plants present in the image, and making them suitable across various machine learning tasks. Here, you will find a comprehensive overview of the dataset, including its contents, annotation process, metadata, characteristics, and availability.

Makeup

NAIR is made-up of 3 broad plant datasets; Weeds (WIR), Cover crops (CCIR), and Cash crops (CIR) each of which can be further divided into two main scene types, Semi-field and true real-world Field.
