Abstract

Linear transformations are carried out on a matrix that represents information such as an image or a communication. In an aspect, the matrix is processed to remove duplicate information. The duplicate information can be duplicate rows, or zero rows. This matrix is then transformed into a modifed matrix, indicating duplicate information is removed to produce a modified matrix.
