Spatial Images Feature Extraction Based on Bayesian Nonlocal Means Filter and Improved Contourlet Transform
Spatial images are inevitably mixed with different levels of noise and distortion. The contourlet transform can provide multidimensional sparse representations of images in a discrete domain. Because of its filter structure, the contourlet transform is not translation-invariant. In this paper, we us...
