Application of the Haar Transform to IR Imagery

Abstract

The author's fast Haar transform algorithm, referenced in a previous report, is analytically shown to elicit signal contrast improvement of digital imagery data. The development of a computer program to measure contrast improvement is explained, and tabular and graphical results of contrast increase are presented. A simulation is also developed to explore the algorithm's ability to improve the signal-to-noise ratio of digital imagery, and tabular results of the decrease of the RMS noise levels and increased signal-to-noise ratios are presented. Finally, the algorithm is run using real infrared imagery data, and picture plots before and after Haar processing are shown.
