Signal information watermarking detection process having matrix coefficients inverse transformed with column length smaller than original column/stored internal memory and watermarking internal memory detected from column peaks.

摘要

The watermarking detection process has an assembly of signal information assembly coefficients. The watermarking is configure in the form of a matrix. There is a step of inverse matrix transform multiplication. The matrix column length produced is smaller than the original matrix column and is stored in an internal memory. Watermarking is detected by detecting peaks on each column assembly whilst the columns are in the internal memory.
