Abstract

Different coding allows for the representation of the signals in a digital form with small word length and at the same time it ensures a specified resolution. The use of differences and delta modulation (DM) for the economical representation and efficient processing of the images needs the development of the existing methods and the working out of simple and fast processing methods in real time. One of the perspective processing methods is the unclear extreme analysis (UEA). Methods of signal compression and reconstruction (in the real time mode) with the use of UEA and DM are simple, economical and fast. The dependence of degree compression and a specified accuracy of the signal reconstruction with the use of UEA, first and secondary 2-D differences, separately and together, are showed in the examples. The influence of the limits of unclearance for them is shown too. This type of compression and reconstruction can be realized with the help of economical and technological devices, especially with the homogeneous computing environments.
