Posted on November 30, 2018 by billcomstock

retroReveal provides documentation and web based image processing algorithms designed to help people discover hidden content. While the current version of the site provides basic assistance with image processing, we will be adding support for collaborative work among scholarly communities in a wide variety of disciplines in the future. retroReveal provides an inexpensive discovery tool to assist people who wish to identify hidden text in their documents for further study. The web based image processing we provide assumes no specialized image editing knowledge, and is designed to be used by a broad spectrum of researchers, scholars, and community members.

 retroReveal.org is hosted by the University of Utah
