For the last 10 years much of my research effort has been in the area of digital video coding, analysis and retrieval. To this end I am involved in the Visual Media Processing Group in the School of Electronic Engineering, and in the Centre for Digital Video Processing, a University designated research centre in DCU which is responsible for

My favourite academic book of all time is Tristan Needham's Visual complex analysis, OUP, 1997.  I had figured out some of the basic ideas myself beforehand, but when I read this, the scales fell from my eyes. If you have ever puzzled over Laurent series,  residues and Cauchy's (various) theorems on complex analysis, and even if you haven't, take a look at this. All formalists beware - it's a maths book with pictures! If you like mathematical understanding through pictures, look up Dynamics - the geometry of behavior by Ralph H. Abraham and Christopher D. Shaw. (There are three volumes and they were pretty expensive the last time I looked).
 
 
 
 
 
 

  If physics is your poison, you have got to read (i.e look at) The cartoon guide to Physics by Larry Gonick and Art Huffmann.

  I am a major fan of Matlab for just about any type of engineering computation prototyping, but at the moment I think it is overpriced.
 
 
 
 

Since I saw my first random dot stereogram, I have been hooked on Stereo Vision and am currently working on low-cost video speed stereo depth capture. Have a go at free-fusing the following stereo pair. You can get "cheat" glasses to do this at Reel 3-D.

  I am interested in spreading the word about Stephen Grossberg to the Computer Vision and Video Coding communities. It would be impossible to describe here the extent of the understanding of the human visual system that he and his colleagues have build up over several decades, so I am simply including two versions of the Kanisza square illusion to act as visual mnemonics:

Philosophically I am probably closest to the Autopoietic position. A  gentle introduction to the topic (or perspective) of autopoiesis can be found in The Tree of Knowledge, The Biological Roots of Human Understanding, by Humberto Maturana & Francisco Varela,  Shambhala, Boston, 1987. A book which was a big influence on me when I was working on my PhD is Pattern Recognition - Human and Mechanical, by Satosi Watanabe, Wiley, 1985.
 
 
 

A love of all things to do with Aeroplanes seems to run in my family. For example, on left is a picture of one of my brothers, Captain Pat Murphy, piloting the Aer Lingus Iolar at Trim Airfield (photo courtesy of Mary Mulligan (nee Ramsbottom)), and right is yours truely with the broad grin of someone who has just finished his first solo, without bending the aeroplane! .

And Finally ...
If you have scrolled down this far, your reward is a schematic interpretation by N.L. Thomas of Kerb Stone 15 at the megalithic monument of Knowth, near Newgrange, about 20 km further down the Boyne Valley from Trim. (Replace the "m" sound in "mouth" by an "n" sound and you have the pronounciation of Knowth). See Irish symbols of 3500 BC, by N.L. Thomas, Mercier Press, 1988 for the background to this interpretation, or the Mythical Ireland site for more information on megalithic Ireland.
