Mg. Bello, A COMBINED MARKOV RANDOM-FIELD AND WAVE-PACKET TRANSFORM-BASED APPROACH FOR IMAGE SEGMENTATION, IEEE transactions on image processing, 3(6), 1994, pp. 834-846
The present work formulates a novel segmentation algorithm which combi
nes the use of Markov random field models for image-modeling with the
use of the discrete wave-packet transform for image analysis. Image se
gmentations are derived and refined at a sequence of resolution levels
, using as data selected wave-packet transform images or ''channels.''
The described segmentation algorithm is compared with non-multiresolu
tion Markov random field-based image segmentation algorithms in the co
ntest of synthetic image example problems, and found to be both signif
icantly more efficient and effective.
