Abstract
The method for video compression to a high degree on the basis of the calculation of motion estimation is based on obtaining complete information and on the structure and dynamic of the inter-frame interaction and its use in video compression procedures. Video films are presented as a series of scenarios, which are examined as a series of scenes, dynamically replacing each other. Scene analysis is presented as a labeled graph of relationships between subjects. Coding of scenes permits consideration of their structure and the structure of subjects by using an adaptive metric. An increase in the degree of compression and improvement in the quality of the images obtained by removal of unwanted artifacts during compression are permitted. The disclosed method checks for conflicting situations during motion estimation, and its reverse-recursive structure provides for their removal. The stochastic nature of the criteria for the proximity of the object is also considered.
