METHOD OF CODING AND METHOD OF DECODING IMAGE SIGNAL, METHOD OF CODING AND DECODING DATA SOURCE, DEVICE TO THIS END AND DATA MEDIA ON WHICH PROGRAMS FOR SAID METHODS ARE STORED

摘要

FIELD: information technology. ^ SUBSTANCE: sequence of Gaussian signal values of an integral signal is entered as coding targets; these signal values contained in the sequence of input signal values are converted to pairs of whole numbers, each having two whole numbers arranged in the order of the input; each pair of whole numbers is viewed as an array point in two-dimensional coordinates and values of whole numbers greater than or equal to zero are obtained as a result of two-dimensional to one-dimensional reflection, where the shorter the distance from each array point to the origin of coordinates, the smaller the value of the array point as a result of reflection; and values of whole numbers are coded using codes which are used to code a data source which corresponds to exponential distribution. ^ EFFECT: efficient coding of different types of common signal sources such as image signals and voice signals using Golomb codes. ^ 18 cl, 21 dwg
