[Special Effects] process

Description: 在数字图像处理中，常常会遇到图像中混杂有许多的噪声。因此，在进行图像处理中，有时要先进行祛除噪声的工作。最常用的祛除噪声的方法是用滤波器进行滤波处理。MATLAB的图像处理工具箱里也设计了许多的滤波器。如均值滤波器、中值滤波器、维纳滤波器等。用户可以很方便的运用一些函数完成数字滤波工作。-In digital image processing, the image often encounter mixed with a lot of noise. Therefore, when the image processing, and sometimes the work to conduct eliminate noise. The most commonly used method is to remove the filter for noise filtering. MATLAB image processing toolbox also designed many of the filters. If the mean filter, median filter, Wiener filters. Users can easily use some digital filtering function completes the work.

[2D Graphic] denoisingFilters

Description: denoising filters such as Average, Median, Gaussian, Wiener, Min-order-statistic, Maxorder-statistic and Median-order-statistic are used. Based on the images obtained by the mentioned filters, it is become obvious clear that for the given noisy image the Min filter acted much better than the other filters. Order-statistic Median and Gaussian filters are the ones that have a second and third good result respectively. That is way can conclude that the existing noise in the given image was Salt noise.-denoising filters such as Average, Median, Gaussian, Wiener, Min-order-statistic, Maxorder-statistic and Median-order-statistic are used.

[Other] Outliers-in-Process-Modeling-and-Identification.r

Description: Model-based control strategies like model predictive control (MPC) require models of process dynamics accurate enough that the resulting controllers perform adequately in practice. Often, these models are obtained by fitting convenient model structures (e.g., linear finite impulse response (FIR) models, linear pole-zero models, nonlinear Hammerstein or Wiener models, etc.) to observed input–output data. Real measurement data records frequently contain “outliers” or “anomalous data points,” which can badly degrade the results of an otherwise reasonable empirical model identification procedure. This paper considers some real datasets containing outliers, examines the influence of outliers on linear and nonlinear system identification, and discusses the problems of outlier detection and data cleaning. Although no single strategy is universally applicable, the Hampel filter described here is often extremely effective in practice.

[matlab] mss_mmse_spzc

Description: In statistics and signal processing, a minimum mean square error (MMSE) estimator is an estimation method which minimizes the mean square error (MSE) of the fitted values of a dependent variable, which is a common measure of estimator quality. In the Bayesian setting, the term MMSE more specifically refers to estimation in a Bayesian setting with quadratic cost function. In such case, the MMSE estimator is given by the posterior mean of the parameter to be estimated. Since the posterior mean is cumbersome to calculate, the form of the MMSE estimator is usually constrained to be within a certain class of functions. Linear MMSE estimators are a popular choice since they are easy to use, calculate, and very versatile. It has given rise to many popular estimators such as the Wiener-Kolmogorov filter and Kalman filter
