PSDmatriisi
PSDmatriisi is a term that appears in the context of image processing and computer vision, often related to the Singular Value Decomposition (SVD) of an image or a related matrix. The Singular Value Decomposition is a fundamental matrix factorization technique that decomposes a matrix into three other matrices. When applied to an image, which can be represented as a matrix of pixel values, SVD reveals important structural information.
The "PSDmatriisi" itself likely refers to a matrix derived from or related to the SVD, potentially a
