COMPRESSION OF VIDEO DATA

An algorithmic solution to the compression of continuous vidoe images containing Navy environmental data such as a weather briefing is proposed. The technique described is an extension to the multiresolutional algorithms used presently for compression, and particularly an extension of the wavelet transform. A company developed technique image analysis system will be coupled to the transform theory to provide the necessary compression to enable transmission of continuous video over low bandwidth communication lines such as HF communication used in ship to ship communications. Because these continuous images can be considered from a three dimensional viewpoint with small changes between frames, the concept proposed is to apply an extended three dimensional transform to those regions where change has occurred.
