Presentation Material

Conference posters

Posters can be a great way to present one’s research, a manner of interaction that is not possible when giving a talk. Here are some of our recent posters that you can download to have a snapshot of our research.

AIC 2005 Poster on “Path-based shadow removal” (Look at our BMVC05 paper for more details)

CVMP 2006 Poster on “The 1.5D Sieve” (Look at our Pat. Rec. Letters paper for more details)

ICPR 2006 Poster on “Simple shadow removal”

CGIV 2006 Poster on “Path-based colour image segmentation”

CIC15 (2007) Poster about “The bright-chromagenic algorithm for illuminant estimation”

ICCV 2007 Poster for the paper “Detecting Illumination in Images”
