Analysis and Extension of the PCA Method, Estimating a Noise Curve from a Single Image

In the article 'Image Noise Level Estimation by Principal Component Analysis', S. Pyatykh, J. Hesser, and L. Zheng propose a new method to estimate the variance of the noise in an image from the eigenvalues of the covariance matrix of the…

Subgeometric rates of convergence in Wasserstein distance for Markov chains

In this paper, we provide sufficient conditions for the existence of the invariant distribution and for subgeometric rates of convergence in Wasserstein distance for general state-space Markov chains which are (possibly) not irreducible. Compared to…

Multiscale Noise Estimation and Removal for Digital Images

Any image, digital or analog, contains not only information from the scene being photographed but also external interferences known as noise. The resulting image is the combination of the ideal image without noise with noise itself. The "ideal image…
