Abstract

The Markov model limited maximum likelihood algorithm is used to analyze the image. Then, the original image block and the image block affected by noise are estimated respectively. Local adaptive regression kernel and principal component analysis were used to extract feature and cluster the image block structure. The original image block's mean value and covariance matrix were computed. Subsequently, by applying weighted averaging techniques to these matrices, the noise reduction estimates for each individual image block could be achieved. The maximum likelihood method is used to make the completely confocal non-correlation, and the Markov random field model is used to limit it. This method can recover the high frequency component of the image well. The seismic response characteristics of fabricated building steel frames are studied. The results show that each group of tests follows the structural system of "block-rib-frame column triple seismic defense system", and its failure mode is one of overall shear failure. The combination of SRC frame and inclined ribbed composite shear wall can not only significantly improve its shear performance, but also obtain better damping effect.
