Glossary

FOI:
Freedom of Information Act.
Forms processing:
Software that automates the process of scanning paper forms, applying recognition technology to recognise the form, extracting data from the form, validating, correcting and exporting the data to a business application.
Fuzzy Logic:
A full-text search procedure that looks for exact matches as well as similarities to the search criteria, in order to compensate for spelling or OCR errors.
GreyScale:
The use of many shades of grey to represent an image. Continuous tone images, such as black-and-white photographs, use an almost unlimited number of shades of grey.
HSM:
Hierarchical Storage Management. Management system whereby data which becomes less active is migrated from expensive hard disks to lower cost mass storage alternatives.
ICR:
Intelligent Character Recognition. An advanced form of OCR technology that may include capabilities such as learning fonts during processing or using context to strengthen probabilities of correct recognition or that can recognise handprint characters.
ISIS:
Specialised interface software used for communication between scanners and computers. See also Twain.
JBIG:
Joint Bi-level Image Group. A new international standard compression algorithm for black and white and halftone image information. A lossless compression algorithm designed to offer compression improvements of up to 180 per cent over CCITT Group 3 and 4.
JPEG:
(Joint Photographic Experts Group) Grouping associated with ITU and ISO which has defined a compression-decompression standard for colour and greyscale image applications. See also MPEG.
JPEG2000:
An image coding system developed by JPEG that uses state-of-the-art compression techniques based on wavelet technology. It is particularly focused on providing improved quality, performance and error resilience for highly compressed images in low bandwidth and noisy transmission environments.
Jukebox:
A machine that allows a large number of optical disks to be held near-line. It consists of disk racks with space for one or more disk drives and one or more robotic pick-and-place mechanisms. The robotic mechanism retrieves the specified disk from the rack, loads it, correctly oriented, into a disk drive, and/or returns the last disk read to the storage rack position.
