The Regularizing Effect of the Golub-Kahan Iterative Bidiagonalization and Revealing the Noise Level in the Data
Regularization techniques based on the Golub-Kahan iterative bidiagonalization vector), where the noise level is unknown. We show how the information from the Golub-Kahan iterative bi...

Noise revealing in Golub-Kahan bidiagonalization as a mean of regularization in discrete inverse problems
. It was shown that high-frequency noise reveals during the Golub-Kahan iterative bidiagonalization in the left bidiagonalization vectors. We present a method that identifies the iteration with ma...

Notes on performance of bidiagonalization-based estimator in image deblurring
Image deblurring represents one of important areas of image processing. When information about the amount of noise in the given blurred image is available, it can significantly improve the performance of image deblurring algorithms. The paper [11] in...
