A Nearly One-to-One Method to Convert Analog Signals into a Small Volume of Data: Second Part 2-D Signals and More

摘要

This article is an extension for 2-D analogue signals (and more) of the methods presented in "A nearly One-to-One Method to Convert Analog Signals into a Small Volume of Data " which was published in an earlier issue. This new conversion method may save the storage space, the bandwidth of the transmitting channels and the necessary energy for transmission. It may be particularly interesting for the space communications and/or information storage but also for TV transmissions to save spectrum, especially for the coming 3-D TV. Once a successful realization of a dedicated software and hardware able to realize the conversion in "real time ", new standard with a better quality and low data volumes may be considered for the 2-D and also for the 3-D signals transmission and/or storage. This conversion method may be considered also as a "public key encryption " and may insure a good (or even very good) security of information. Due to the high sensitivity of parameters of this coding/decoding procedure, especially for higher compression factors, and to the big number of the used parameters, this method may be also considered as a strategic information technology.
