Jacobaea vulgaris and meadow image classification dataset (binary)

General Information

Instances in the Jacobaea vulgaris class: 895Instances in the Meadow class: 9141Image sizes from 77x77 to 817x817 pixels on three color channels (RGB)

Data Generation and Source

The images in this dataset were taken as part of the project “UAV-basiertes Grünlandmonitoring auf Bestands- und Einzelpflanzenebene” (engl. “UAV-based Grassland Monitoring at Population and Individual Plant Level”), financed by the Authority for Economy, Transport, and Innovation of Hamburg. In September 2018, flights with an octocopter were conducted over two extensively used grassland areas in the urban area of Hamburg. The multicopter flew in a height of circa 11 meters and took pictures with a ground resolution of approximately 3,18 mm/pixel. Additional information about the process of image generation for this dataset are to be found in the relevant papers written by P. Zacharias: 1) UAV-basiertes Grünland-Monitoring und Schadpflanzenkartierung mit offenen Geodaten [p. 45–53] and 2)  UAV-basiertes Grünlandmonitoring auf Bestands- und Einzelpflanzenebene.

Additionally, to the images of Jacobaea vulgaris taken by the UAV, the dataset includes images of Jacobaea vulgaris plants from the internet (included in the total 895 images; e.g. images 'jkk0523.jpg', 'jkk0527.jpg'). Furthermore, some of the images of the Jacobaea vulgaris plants have been rotated, further cropped or a filter has been applied. The exact number of augmentations made is unknown. As there are augmented images included in the datasets -which makes the dataset useful for training and validation- a use of the dataset for testing purposes is not recommended due to the risk of data leakage.
