Pl@ntNet-300K-v2 image dataset

Pl@ntNet-300K-v2 is an image dataset designed for evaluating set-valued classification methods. It is derived from the Pl@ntNet citizen observatory database and comprises 306,087 images spanning 1,000 plant species.The new version provides improved images resolution and better naming for the species.

Key Features

The dataset reflects two notable characteristics, intrinsic to both the image acquisition process and the morphological diversity of plants:

• Strong class imbalance: A few species account for the majority of images.
• Visual similarity: Many species are visually indistinguishable, posing challenges even for expert identification.

These attributes make Pl@ntNet-300K-v2 particularly suited for benchmarking set-valued classification approaches.

Dataset Structure

Image Organization

Images are partitioned into train, test, and val sets, stored in directories labeled 0000 to 0999.
