Dataset description

This dataset contains microscopic images and videos of pollen gathered between Feb. and Aug. 2020 in Graz, Austria.

  • Pollen images of 16 types: ...images_16_types.zip

    • Acer Pseudoplatanus
    • Aesculus Carnea
    • Alnus
    • Anthoxanthum
    • Betula Pendula
    • Brassica
    • Carpinus
    • Corylus
    • Dactylis Glomerata
    • Fraxinus
    • Pinus Nigra
    • Platanus
    • Populus Nigra
    • Prunus Avium
    • Sequoiadendron Giganteum
    • Taxus Baccata
  • Pollen video library ...pollen_video_library.zip

    • Each type of pollen is in a separate folder, there may be multiple videos per type.
    • In each pollen folder, we included images cropped from the videos by YOLO object detection algorithm trained on a subset of pollen images as described in [1].
    • Cropped file name structure [Video file name]_[TrackingID]_[Image index of a grain]_[Frame index in video]
      • Example, if a grain has 5 images, the file name would be:
         Anthoxanthum-grass-20200530-122652_0000000_001_00001.jpg
         Anthoxanthum-grass-20200530-122652_0000000_002_00002.jpg
         ...
         Anthoxanthum-grass-20200530-122652_0000000_005_00005.jpg
        
  • Field data over 3 days are gathered in Graz in spring 2020. ...pollen_field_data.zip

  • Sample code to load the data and visualize the images is in ...plot_pollen_sample.py. Download and extract the file ...images_16_types.zip in the same folder as ...plot_pollen_sample.py to run the example.

Dependecies:

  • opencv
  • numpy
  • matplotlib
