This paper proposes to apply Bayesian principle to clustering matting components in spectral matting. Spectral matting is a useful and effective technique for digital image matting. A crucial issue of spectral matting is how to cluster the computed matting components, which compose the final alpha matte. In this paper, a new clustering strategy based on Bayesian decision theory is proposed to solve...
Fault pattern and mechanism of Software-intensive equipment are discussed and thought of application on fault diagnosis in Software-intensive equipment by HMM is presented. Based on the HMM theory, the algorithm of which is modified by multi-state reliability analysis to evaluate the state of Software-intensive equipment fault pattern. The result shows that the method presented can succeed in recognizing...
A 2.5D multifrequency large signal beam-wave reaction code of TWT based on the field theory is developed for crossmodulation and intermodulation products, in which space charge fields are obtained through solving discrete Helmholtz equations with the help of Particle-in-cell method. Two-tone experiment and simulation of L band space helix-TWT shown that a good agreement in CM and IM products.
By the method of tangential velocity in the paper, The error model was established, the analysis software was developed, some error patterns and decisive parameters were analyzed, the measures to amend, additionally, were proposed. In order to solve the difficult problem of synthetic control for trajectory position and motion, studied the spatial and time characteristics of trajectory movement and...
