Odeuropa Dataset of Smell-Related Objects

<strong>Odeuropa Dataset of Olfactory Objects</strong> This is version two of the Odeuropa Dataset of Olfactory Objects which has been released as part of the Odeuropa project .<br> It contains bounding box annotations for smell-active objects in historical artworks gathered from various digital connections.<br> The smell-active objects annotated in the dataset either carry smells themselves or hint at the presence of smells.<br> The dataset provides 36663 bounding boxes on 4696 artworks in 169 object categories.<br> An additional csv file contains further image-level metadata such as artist, collection, or year of creation. <strong>How to use</strong> Due to licensing issues, we cannot provide the images directly, but instead provide a collection of links and a download script. To get the images, just run the `download_imgs.py` script which loads the images using the links from the `metadata.csv` file. The downloaded images can then be found in the `images` subfolder. The overall size of the downloaded images is c. 600MB. The bounding box annotations can be found in the `annotations.json`. The annotations follow the COCO JSON format, the definition is available here. The mapping between the `images` array of the `annotations.json` and the `metadata.csv` file can be accomplished via the `file_name` attribute of the elements of the `images` array and the unique `File Name` column of the `metadata.csv` file, respectively. Additional image-level metadata is available in the `metadata.csv` file.
