Conversion Notes

All images that were originally in color were converted to grayscale using Rec. 601:

0.299 R + 0.587 G + 0.114 B

Original images may be cropped and/or resized to fit into one of the predefined image sizes. All images are stored as uint8-PNG images. For some images this required rescaling the data.
