- Abstract
The non-deterministic characteristics of the floating coding scheme for the method of cryptocompression representation of images in a differentiated basis are estimated. Namely: eestimation of the number of image elements that form code constructions; estimation of the length of the formed code structures. It is proved that code constructions are formed on a variable (predetermined) number of elements of the original image. In the formation of the code of the information component of the cryptocompression representation of images in a differentiated basis with a codeword length of 64 bitsmay involve from 8 to 64 or more elements of the original image. Code constructs are formed of variable (predetermined) length, which ranges from 57 to 64 bits with a codeword length of 64 bits Without an open system of grounds, it is impossible to priori predict the length of any code of the informational component of the cryptocompression image representation. Moreover, it is impossible to break all information component into separate blocks corresponding to separate code constructions. The number of elements that form the codes of the information component of the cryptocompression representation of images, and the lengths of the information components themselves depend only on the initial values of the image elements. They are different for different images and for different color planes within the same image.
