METHOD OF BI-DIRECTIONAL LEXICOGRAPHY FOR NONEQUILIBRIUM POSITIONAL ENCODING OF VIDEO SEGMENTS

The article demonstrates that when unmanned platforms are used to collect video information, a disparity arises between the performance of wireless infocommunication systems and the intensity level of the information streams that must be processed and transmitted. In general, to maintain the required quality of video data under such a disparity, the following measures are necessary: increasing the performance of infocommunication systems (ICS); improving the efficiency of video data compression systems; and ensuring robustness against interference. Currently, a number of video compression methods have been developed. Functionally, they can be divided into two classes depending on the use of parameter control technologies within models that detect and reduce psychovisual redundancy. It is argued that the critical limitation of the first class of methods is the increase in information loss when practical compression levels must be achieved for information-rich areas of video data. The impact of this limitation on compression efficiency can be mitigated by developing methods from the second class. This class includes methods that eliminate redundancy of a structural-positional or statistical-positional nature. One of the main representatives of structural-positional encoding methods is the variable-weight positional encoding technology, also known as Nonequilibrium Positional (NQP) encoding. These methods are capable of adapting to the content of video segments based on their structural and positional characteristics. In this case, regardless of the encoding direction, there exists a dependency between the weight of higher-order NQP-number elements and the bases of lower-order elements. This leads to an increase in the weight of elements during encoding. A critical threshold arises if the encoding direction is chosen inappropriately, considering the structural characteristics of the video segments within the range of permissible values. Therefore, it is proposed to develop a more adaptive version based on a strategy of using bi-directional lexicography during NQP encoding. The article outlines the main stages for creating such bi-directional lexicography based on adaptive selection of the indexing direction of element values within the operational range of the NQP basis.
