This randomized SVD algorithm returns approximations to the top k right (or left) singular vectors of the image matrix. Our goal is to compare these ...
We experimentally evaluate the accuracy and speed oft his randomized algorithm using image matrices and three different sampling schemes. Our results show that ...
The algorithm samples a small number of rows (or columns) of the matrix, scales them appropriately to form a small ma- trix S and computes the singular value ...
TL;DR: In this article, singular value decomposition (SVD) and pseudoinverse techniques are used for image restoration in space-variant point spread functions ( ...
