Svd and eigendecomposition
Splet(SVD) and Eigenvalue decomposition (EVD) is presented. Considering that the SVD and EVD are complex and ex-pensive operations, to achieve high performance with low computing complexity, our approach takes full advantage of the combination of parallel and sequential computa-tion, which can increase efficiently the hardware utiliza-tion. SpletThis video describes how the singular value decomposition (SVD) can be used to efficiently represent human faces, in the so-called "eigenfaces" (Python code,...
