RESEARCH: Sigmedia

Sigmedia was started in 1998 when Dr. Anil Kokaram joined the EEE Department at Trinity College as lecturer. We are involved in a very wide range of research activities centred on digital signal processing technology.

Bleed-Through Database

The images contained here form a database that is designed to be a resource for people working in the field of digital document restoration, and more specifically on the problem of bleed-through degradation. It consists of a set of 25 registered recto verso sample grayscale image pairs, taken from larger manuscript images, with varied degrees of bleed-through.

See the Bleed-Through Database page for more information.
