Abstract:
1. A method for data compression/decompression comprising subjecting an electrical signal encoded with data to a computer processor executable method for transforming an input data set represented by a 16 by 16 matrix of a first domain into an output data set represented by a 16 by 16 matrix of a second domain, comprising the steps of: obtaining by a computer processor from a persistent storage media a first 16 by 16 transfer matrix, wherein the first 16 by 16 transfer matrix is orthogonal; computing by a computer processor a transpose of the first 16 by 16 transfer matrix; computing by a computer processor an intermediate result by matrix-multiplying the input data set by the transpose of the first 16 by 16 transfer matrix; and computing by a computer processor the output data set by matrix-multiplying the first 16 by 16 transfer matrix by the intermediate result; wherein the first 16 by 16 transfer matrix is
