Compensations or eliminations of the systematical error are indispensable for designing an accurate real-time instrumental system. In virtue of an elaborate object function, a new recursive model for the state and the systematical error is developed based on semi-parameter modeling. Considering of the separable character of the new model, an improved dual unscented filter (DUKF) is developed, which...
Traditional Basis Pursuit model is adapted to signal de-noising under additive Gaussian noise. Based on the different fitness error term, one new kind Extended Basis Pursuit De-Noising (EBPDN) model is brought forward and applied into salt-and-pepper noise removal. A comparison study of performance of the median filter, the peak-and-valley filter, the detail preserving filter and the EBPDN model is...
