To solve this isolated problem, we proposed a novel multi-resolution network and stochastic orthogonal learning method. More specifically, the proposed method include three functional steps: (i) we emphasize the features using retinex model-based image-enhancement [], (ii) we track the bonnet region using an optimized correlation filters [], and (iii) we engage this region and image using the    Multi-agent stochastic level set method.

In this paper we study a one-dimensional, nonlinear stochastic differential equation when small amplitude, long-period forcing is applied. The equation arises in the theory of the climate of the earth.

We find that the cooperative effect of the stochastic perturbation and periodic forcing lead to an amplification of the peak of the power spectrum, due to a mechanism that we call stochastic
