Aimed at the excellence and shortcoming of the standard median filtering algorithm and the adaptive median filtering algorithm as well as center weighted median filtering algorithm, a new adaptive weighted median filtering algorithm is proposed in this paper. The new algorithm first takes a decision whether the pixel under test is noise or not by comparing… (More)

In this paper, the method of upper and lower solutions and the Schauder fixed point theorem are used to investigate the existence and uniqueness of a positive solution for a class of nonlinear fractional differential equations with non-monotone term. An example is also given to illuminate our results. 2000 MSC: 34B15 • 34B18

In this paper, the parallel decoupling algorithm is given to solve the block tri-diagonal linear equations. The solution process of the algorithm are as follows: Firstly, decoupling method is used to decompose the huge block tri-diagonal linear equations to even number small block tri-diagonal ones with balancing loadings, and sum of the small blocks… (More)
