Paper Abstract
A class of adaptive data compression routines is presented based on data dependent transformation. The
current class of methods identifies improved information association by utilization of eigen-vectors rather
than the eigen-values based prioritization. The Karhounen-Loeve, KL, transform limits the importance of
the data by the limitation of the eigen-values associated with covariance of data, this leads to the
truncation of the eigenvectors by their energy levels. Therefore, the remaining data in the KL transform
method limits the information that can be represented to those data contents that represent the majority of
signal energy as identified by the prioritized eigen-values of the data covariance matrix. The method
presented in this work retains desired data structure and enables a more exact representation of the
information in the data leading to the preservation of data that can contain significantly relevant
information even-though its energy contents may be relatively low as compared to other bases. This work
presents a description of this idea along with an error analysis relative to the original data. The simulation
work applies the technique to data from an image by association of neighboring data samples. A
discussion of the simulation results though relevant metrics completes the analysis in this work.
