For more information 5. The data files in this directory contain images used in the Los Alamos National Laboratory script identification project. If you make use of these images, please acknowledge Judy Hochberg of Los Alamos National Laboratory as their source. Image nomenclature The images are divided into training, test, and challenge images, according to their usage in our project. The tar files themselves are not compressed because the individual images all are.
Resolutions are a bit of a mess.
When we scanned in images ourselves, we used 300 or 400 dpi for training and test images, and 300 dpi for challenge images. We don't know which images he scanned at 200 dpi, and which at 300. Here is summary information on resolutions for the training and test images. For more information The languages, sources, and features of the images are described in two tables which are in the postscript file tables.ps in this directory.
