Spatial redundancy reduction of slow scan TV images

This paper deals with the application of a spatial redundancy reduction algorithm to slow scan TV images acoustically transmitted from an untethered submersible. The goal of this research effort is to implement a bandwidth reduction technique which provides suitable data compression, fidelity and channel error tolerance so that meaningful images are received. These images must allow the remote operator to direct the submersible through its tasks of navigation, inspection, maintanence and repair of submerged structures.
