Note that all images are resized to a fixed height of 128 pixels. ### Languages All the documents in the dataset are written in English. ## Dataset Structure ### Data Instances ``` { 'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=2467x128 at 0x1A800E8E190, 'text': 'put down a resolution on the subject' } ``` ### Data Fields - `image`: a PIL.Image.Image object containing the image. Note that when accessing the image column (using dataset[0]["image"]), the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the "image" column, i.e. dataset[0]["image"] should always be preferred over dataset["image"][0]. - `text`: the label transcription of the image.
