Claim One:
1. An apparatus for compressing an image; comprising: a principal component analyzer configured to iteratively perform a Principal Component Analysis (PCA) on a selected portion of the image, wherein each resulting orthogonal basis set has “N” basis vectors; a matrix rank evaluator to evaluate the rank of each orthogonal basis set; the principal component analyzer further configured to iteratively perform the PCA based on the rank of an initial orthogonal basis set as evaluated by the matrix rank evaluator, whereby the initial orthogonal basis set exhibiting a low rank results in a negative determination with respect to the performance of a subsequent PCA and vice versa; a puncturer configured to puncture selected dimensional components of the orthogonal basis set resulting from each PCA of the selected portion of the image, without removing any of the associated “N” basis vectors thereof; a truncator configured to remove selected basis vectors of a final one of the resulting orthogonal basis sets of the principal component analyzer, thereby forming a truncated basis set for compression of the selected portion of the image; a projector configured to project the image onto the truncated basis set thereby obtaining coefficients of the selected portion of the image, relative to the truncated basis set.
