MIL-STD-188/199, DEPARTMENT OF DEFENSE INTERFACE STANDARD: VECTOR QUANTIZATION DECOMPRESSION FOR THE NATIONAL IMAGERY TRANSMISSION FORMAT STANDARD (NIFTS) (27 June 1994)., This standard establishes the requirements to be met by NITFS compliant systems when image data are decompressed using the VQ compression algorithm. This allows NITFS-compliant systems to accept and decompress data that are compressed using a VQ compression scheme. This standard describes the VQ compression in the general requirements section, but does not fully describe the steps for compression. The steps involved in decompressing images compressed with VQ are fully described by this standard.
