Details are given here of presentations made at recent Imaging Science Group events, converted, where possible, into a web-friendly format.
Good Picture 2007: The Imaging Chain
Digital Futures 2007: Visual Aspects of Imaging
Good Picture 2006: Management and Manipulation
Good Picture 2005: Inside Digital Output
Digital Futures 2005: Quantitative Aspects of Imaging
Good Picture 2004: Digital De-Mystified!
DIY Photoshop 101
Dr. Rob Jenkin, Cranfield University
We all rely on the marvellous results produced by packages such as Adobe
Photoshop™ and Paintshop Pro™ - but how many of us know
what's under the bonnet? This talk lifts the lid on one of the core
processes these packages use and encourages you to experiment by making
your own. We'll explore what actually happens when you sharpen, blur
or find edges in an image. Strangely we'll find they are all the same
flavour. Uprate your Metro to a Ferrari by adding convolution to the
tank!
Good Picture 2003: Assessing the Quality of Digital Images and Systems
Image Quality: Meanings, Minefields and Mastery
Professor Ralph Jacobson, University of Westminster
An essentially non-mathematical overview of various issues relating
to image quality, including working definitions, transferability of
concepts from conventional to digital systems, physical (objective)
and psychophysical (subjective) measures.
Digital Cameras - Lovely Colour Isn't It?
Professor Geoff Attridge, University of Westminster
An outline of the reproduction of colour by digital photography, addressing
the characterisation of digital cameras in terms of the "colorimetric
accuracy of colour reproduction". Important limitations of colour reproduction
are also be identified.
Digital Cameras - Choosing and Using
Dr. Mike Pointer, National Physical Laboratory
A review of the major decisions that must be made in order to choose
a digital camera. The issues described include the concepts of pixels,
resolution and compression, as well as taking the picture, downloading
the stored image, and viewing and editing the image.
Archival Image Quality, Storage and Migration Strategies (0.9Mb
Acrobat file)
Dr. Sophie Triantaphillidou, University of Westminster
An introduction to the processes involved in the digitisation, display
and storage of image collections and archives. Description of device
characterisation and calibration proceduresare discussed, along with
the important issues of image encoding, file format, physical storage
and data migration.
