4.3.1Gaussian mixture model a) Algorithm's principleGaussian Mixture Model(GMM) is a statistical model expressed by a mixed density that is used to estimate parametrically the distribution ofrandom variables[251].GMMis a parametricprobability density functionwhich is usually modeled, inEq. (20), as...
These integrals are the average values of different operators evaluated using a mixed basis set of HGBF of every order and centrature. The structure of the HGBF is the following: (69)g(r)=g(u,v,w;a,R;r)=N∂u+v+w∂Xu∂Yv∂Zw2απ3/4exp−α(r−R)2 where R≡ (X,...
Based on the Gaussian mixture model wavelet denoising method and combining with characteristics that median filtering has better effect on impulse noise denosing, the two methods are applyed to the image denoising which contains Gaussian pulse mixed noise. Matlab is used for algorithm simulation and ...
In this paper, we propose a frame-based iterative algorithm to restore images which are corrupted by mixed Gaussian and impulse noise, under the assumption that the image region corrupted by impulse noise is unknown. The removal of mixed Gaussian and impulse noise by our proposed algorithm is sp...
Such ‘mixed’ patient samples may hinder identification of effective, individually targeted clinical management. Moreover, the presence of subgroups impairs the development of novel treatment strategies, as potentially important clinical effects may be masked by unknown variance in the clinical sample of...
For example, a denoising model trained for AWGN removal is not effective for mixed Gaussian and Poisson noise removal. This is intuitively reasonable because the CNN-based methods can be treated as general case of Eq. (4.3) and the important data fidelity term corresponds to the degradation ...
Allosteric regulation was modeled using a mixed inhibition mechanism, which extends the rate law from equation (1) as follows: MathML with [I] being the inhibitor concentration, K i the binding rate of the inhibitor to the enzyme and K ii the binding rate of the inhibitor to the substrate...

The hard assignment is usually problematic because of the complex structure of food samples, especially in the case of imaging wheat kernels with mixed pixels at the boundary of germ and endosperm. Soft clustering algorithms can resolve this issue but has been scarcely applied in the HSI food ...
