This paper presents a novel framework for gradient
vector flow for object segmentation in colour images.
The work extends the results reported earlier in , 
for colour images. In order to evaluate the performance
of the colour gradient vector flow with respect to
intensity based snakes, experiments were conducted on
colour images. The results show that the proposed
snakes successfully find contours and perform better
than the corresponding version that considers intensity
