By using Wavelet Domain Hidden Markov Tree HMT model
the image segmentation resulted in dim edge components and phenomena with singularity and diffusion.Because the singularity in the image of high dimension was fully captured by the Contourlet transformation
the paper presents a new algorithm of multi-scale image segmentation based on the Contourlet transform of domain Hidden Markov Tree model.This algorithm was initially through image Contourlet transform to obtain transform coefficients
