Multiresolution Markov Models for Signal and Image Processing - Willsky (2002) (6 citations) (Correct)
.... and other boundary like features (see, for example, 132, 234] approaches that use non Gaussian models in order to better capture the heavy tail nature of imagery (for example the generalized Gaussian models studied in depth in [41] and an array of procedures using wavelet transforms (e.g. [104, 301, 57, 2, 68, 330, 80, 192, 193, 261, 59, 281, 58, 333]) For this latter set of methods the general idea is to exploit the localization properties of wavelets to allow much easier and more transparent adaptive processing in order to minimize distortion of important image features while removing noise. As we will see, some of these methods explicitly ....
....heavy tailed product that is observed. Optimal estimation for any of the choices of distribution mentioned in this paragraph corresponds to performing nonlinear operations on individual wavelet coe#cients. Among the algorithms that result from such models are so called wavelet shrinkage algorithms [104, 301, 57, 2, 68, 330, 49, 192, 251, 193]. As described in [80] such independent mixture models result in very simple nonlinear operations on individual wavelet coe#cients for optimal estimation. Moreover, both the discrete state hidden models as well as the continuous ones in [333] open the door to building MR models on trees that not ....

....transform, i.i.d. noise is spread out equally over all coecients. Selecting the coecients with the largest magnitude therefore removes most of the noise, while preserving the essential image information. Some of these threshold or more general shrinking procedures are based on a Bayesian model [1, 9, 31, 33, 10]. The sparsity of a wavelet representation follows from the decorrelating properties of this transform. This decorrelating is however not complete: a wavelet transform is also a multiscale data representation and the coe cients at subsequent resolution levels tend to be correlated: image ....
....from zero to one. The last image is binary: black pixels correspond to coecients that are preserved by a minimum GCV threshold. This selection is based on local regularity (magnitude) and shows far less geometrical structure. 25 quently the design of the conditional model. Unlike the labels in [9, 12], a label one in our algorithm means that the corresponding noise free coe cient is certainly larger than . The conditional model is explicitly inspired by the idea of nding the optimal diagonal projection of [14] We do not compute a posterior mean E(V s jW ) but rather a posterior expected ....

....coefficients are predominantly local. The primary properties give the wavelet coefficients of natural images significant statistical structure, which we codify in the following secondary properties [4] S1. NonGaussianity: The wavelet coefficients have peaky, heavy tailed marginal distributions [5, 6]. S2. Persistency: Large small values of wavelet coefficients tend to propagate through the scales of the quad trees [7, 8] NonGaussianity follows immediately from Energy Compaction (P4) Persistency follows from the Edge Detection (P3) and Multiresolution (P2) properties. These secondary ....
....denoising performance, as seen from Fig. 2 and column 1 of Tables 1 3. In contrast to other hidden Markov model techniques in the literature, the uHMT is simple and easy to use. The uHMT offers the performance of a complicated model with the computational efficiency of a simple model. In [5], shrinkage rules are introduced using a two state independent Gaussian mixture model for the prior on the wavelet coefficients. A Generalized Gaussian distribution (GGD) with auto regressive dependencies between neighboring coefficients (both within and across scales) is used to model wavelet ....
