Leafsnap Dataset

To promote further research in leaf recognition, we are releasing the Leafsnap dataset, which consists of images of leaves taken from two different sources, as well as their automatically-generated segmentations:

  1. 23147 Lab images, consisting of high-quality images taken of pressed leaves, from the Smithsonian collection. These images appear in controlled backlit and front-lit versions, with several samples per species.
  2. 7719 Field images, consisting of "typical" images taken by mobile devices (iPhones mostly) in outdoor environments. These images contain varying amounts of blur, noise, illumination patterns, shadows, etc.

The dataset currently covers all 185 tree species from the Northeastern United States.

If you use this dataset, please cite the following paper:

NOTE: The dataset released here doesn't exactly match that used to compute results for the paper, nor the currently running version on our servers.

Data format


The included leafsnap-dataset-images.txt file contains a listing of all the images, in tab-separated format (tsv). The first line is the header row, which describes each column:

    file_id    image_path   segmented_path    species    source
    

Each line lists information about a single image. There are 5 fields, which are separated by tabs:

  1. A unique numerical id for each image. These are not guaranteed to be consecutive or in order. They will not change over future versions of the dataset.
  2. The path of the original image.
  3. The path of the segmented version of the image. Note that where segmentation fails, the images might be completely black. In our running system, we have an automated check to discard such images from inclusion in the dataset for recognition.
  4. The scientific name of the species of the image. Note that these can have spaces and hyphens, and are in mixed case.
  5. The source of the image. This is either lab or field.
