Abstract

In this work the approach to recording, storing and associative retrieval of multimedia information is proposed. For this purpose the method for recording and storing the information on the trajectories of the nonlinear dynamic systems is used. Principles of recording, allowing to retrieve the desired record from the database of audio records by an arbitrary piece of the record we are looking for, are proposed. Methods for optimization of the proposed principles by the CPU time and amount of memory used are developed. Described principles are implemented in Matlab software environment. The results of investigation of the proposed algorithms are given and analyzed.
