In this paper, based on the GM-APD lidar denoising model of fractional-order total variation (FOTV), the spatial relationship and similarity relationship between pixels are obtained by using a spatial kernel function and range kernel function to optimize the fractional diffe...
This paper proposes a fractional-order total variation image denoising algorithm based on the primal-dual method, which provides a much more elegant and effective way of treating problems of the algorithm implementation, ill-posed inverse, convergence rate, and blocky effect. The fractional-order tota...
In this paper, an improved infrared and visible image fusion method via visual saliency and fractional-order total variation is proposed. First, the infrared and visible images are fused through the saliency map to obtain a fused image, and then the fused image and an selected original image ...

By combining fractional-order differential theory with total variation method, a new image denoising method is proposed. The new method, while effectively inheriting these advantages, uses the fractional-order differential amplitude-frequency and effectively. Simulation results which we have got show that...

where Dtα is the fractional derivative in Caputo sense of order α∈(0,1], the state variable is a positive vector of m elements u1,…,um, and f:Rm⟶Rm is a function of class C1. Definition 6.1 (29) Let u∗ be an equilibrium point of system (6.1) such that Θ(u∗) a...
2 provides a comprehensive view of the variation in different compartments over time, utilizing a fractional order of 0.45 and a fractional dimension of 0.99. Fractional orders are particularly effective in capturing complex dynamics that cannot be fully described by classical integer-order models. By...
