| Abstract: | Nonsubsampled contourlet transform is a new multi-scale multi-resolution powerful analysis tool.An unsupervised segmentation algorithm for color image is proposed based on nonsubsampled contourlet transform.Firstly,for nonsubsampled contourlet transform shift invariance,multi-scale edge is extracted in transform domain by using gradient vector method.Then,local low-frequency energy texture features and high-frequency multi-scale Zernike moments texture features are extracted from low-frequency sub-band and ... |
