We are very happy to announce that the Colour and Visual Computing Symposium 2013 (CVCS 2013) will take place in Gjøvik, Norway, on 5-6 September 2013. This will be the seventh time that the Norwegian Colour and Visual Computing Laboratory at Gjøvik University College (GUC) organizes such an event. This edition of the symposium follows up on the success achieved by the previous runs, of the biannual Gjøvik Colour Imaging Symposium (GCIS), from 2003 to 2011. The GCIS has attracted a growing number of participants and provided a platform for fruitful discussions and exploration of recent theoretical advances and emerging practical applications of colour and visual information processing. The CVCS 2013 symposium will contain a rich program of tutorials, keynotes, invited, and regular talks on a wide variety of colour imaging and visual computing topics given by young researchers and well-known international experts in the field.
