We propose an efficient and accurate wavelet-based noise estimation method for white Gaussian noise in video sequences. The proposed method analyzes the distribution of spatial and temporal gradients ...

The imputation of the Multivariate time series (MTS) is particularly challenging since the MTS typically contains irregular patterns of missing values due to various factors such as instrument ...

Both Fickian-but-not-Gaussian diffusion (FnGD) and anomalous diffusion have been observed in various heterogeneous systems. It remains unclear whether FnGD is an independent diffusion process and what ...
