Solving a system of linear equations in python implements the direct decomposition method (Doolittle, Kraut, chasing method)

1. Doolittle decomposition The Doolittle decomposition method is a method of decomposing a matrix into a lower triangular matrix L and an upper triangular matrix U. It is a special form of LU decomposition and is commonly used in calculations such as solving systems of linear equations and matrix inversion. The basic concepts of Doolittle […]

Matrix singular value decomposition – information compression and noise reduction (python)

Matrix singular value decomposition – information compression and noise reduction (open_cv) ? The blogger took a mathematical modeling class today, and the teacher talked aboutThe singular value decomposition of a matrix can be used for image compression. When bloggers learned linear algebra, they did not expect that singular value decomposition could be used in this […]

Compress images using singular value decomposition (SVD) (python implementation)

Singular value decomposition principle of image compression Images are stored in the form of matrices in the computer, so digital images (pictures) can be analyzed and processed using matrix theory knowledge and algorithms. Brief description of the principle Color pictures have 3 layers, which display 3 channels (red, green, and blue) respectively. Color pictures require […]
