Animations Brought to Life

Published on 28 July 2008
Although animated characters can now "learn" to lip sync when human speech is added to the characters, they have not been able to laugh, cry, yawn or sneeze realistically. Now, following research carried out by Dr Cath Holt from Cardiff University, and Dr Darren Cosker from the University of Bath, animated characters will be able to realistically mimic these vocalisations.

They have developed software capable of recognising such sounds Optical motion capture techniques were used to record facial expressions of people sneezing, laughing etc. The researchers then recorded vocalisations of these expressions and developed software to correlate these audio features with the relevant facial expressions.

The result of this research means that a computer generated animation will be able to automatically emulate human expressions such as laughter.
