The third, fourth, and fifth columns give automatic noise estimates using the median/3 ? clipping method, the iterative multiresolution support method, and the block method. The excellent estimation capability of the iterative multiresolution support method can be seen: the fourth column values are very close to the first column values.Cited by: 116

AUTOMATIC NOISE ESTIMATION 195 1998 PASP, 110:193–199 Fig. 1.— Multiresolution support representation of a spiral galaxy 2.4. Algorithm for Determining the Multiresolution Support The algorithm to create the multiresolution support is as follows: 1. We compute the wavelet transform of the image. 2. We estimate the noise standard deviation ...

Automatic Noise Estimation from the Multiresolution Support: Authors: ... Detector noise is ever present and must be determined for high-quality image filtering or compression. We also show that the method can be used for very high quality cosmic-ray hit removal. Our method is based on a multiresolution transform of the image, the à trous ...

An algorithm for automated noise estimation is discussed in Starck and Murtagh (1997). 2. Multiresolution Support. This describes in a logical or boolean way if an image I contains information at a given scale j and at a given position (x,y). If M (I) (j,x,y) = 1 (or ), then I contains information at scale j …

In this study a wavelet-based multiresolution analysis technique (WMAT) is proposed for reducing noises induced by complex uncertainty. The approach is applied to a river water quality simulation system for showing its practicability in data cleaning and parameter estimation.Cited by: 60
