Aerospace Contributions to Image Data Compression Techniques

Aerospace had developed several new and alternative high-quality image-data compression techniques during the last 20 years, mostly for use with multispectral and hyperspectral imaging systems. A few highlights include:

• Split-Radix Discrete Cosine Transform, U.S. Patent 5,408,425, 1995.
• Modulated Lapped Transform Method, U.S. Patent 5,859,788, 1999.
• Merge and Split of Fourier Transformed Data, U.S. Patent pending.
• Merge and Split of Hartley Transformed Data, U.S. Patent pending.
• Merge and Split of Discrete Cosine Transformed Data, U.S. Patent pending.
• Merge and Split of Discrete Sine Transformed Data, U.S. Patent pending.
• Merge and Split of Karhunen-Loeve Transformed Data, U.S. Patent pending.
• Merge and Split of Generalized Transformed Data, U.S. Patent pending.
• Multiple Description Transmission and Resolution Conversion of Compressed Data, Aerospace Invention Disclosure, 2002.
• Lossless Discrete Cosine Transform with Embedded Haar Wavelet Transform, Aerospace Invention Disclosure, 2002.
• Lossless Modulated Lapped Transform with Embedded Haar Wavelet Transform, Aerospace Invention Disclosure, 2002.
• Extended Haar Transform and Hybrid Orthogonal Transform, Aerospace Invention Disclosure, 2003.
• New Lifting Scheme in Wavelet Transforms, Aerospace Invention Disclosure, 2004.
• Fast Adaptive Lifting Scheme in Wavelet Transforms, Aerospace Invention Disclosure, 2004.
