Abstract :
A new segmentation-based lossless compression method is proposed for colour images. The method exploits the correlation existing among the three colour planes by treating each pixel as a vector of three components, and performing region growing and difference operations using the vectors. The method performs better than the JPEG standard by an average of 0.68 bit/pixel with a 12 image database
