Historical Map Annotations for Text Detection and Recognition
-
Description
-
This data is set designed for testing the performance of text/graphics separation and character recognition algorithms on text in scanned historical map images. Thirty one maps from the nineteenth and early twentieth centuries (1866–1927) were chosen from nine atlases in the David Rumsey Map Collection (http://davidrumsey.com). Most maps are of individual U.S. states, though some are regional and one is of the entire U.S.; most feature little handwritten text. The original MrSid files are converted into uncompressed TIFF images for a manual annotation, stored in JSON format. The authors gratefully acknowledge the David Rumsey Map Collection as the source of the map images, which come with the following notice: Images copyright © 2000 by Cartography Associates.

Wood Anatomy of Hydrophyllaceae. I. Eriodictyon
-
Description
-
Hydrophyllaceae is a characteristically herbaceous family; only Eriodictyon Benth., Wigandia H.B.K., and the monotypic Turricula Macbr. can be considered woody (stems attaining a diameter of more than 1 em). Are plants such as these relicts from a woody ancestry, or is the family secondarily woody?
