Latest Patents

Kovalev's latest patents demonstrate a deep understanding of video data processing and adaptation to varying contexts. The first patent, titled "Method and apparatus for compression and decompression of still and motion video data based on adaptive pixel-by-pixel processing and adaptive variable length coding," introduces a novel approach to encoding each pixel as static, new, or directionally estimated. This method enhances performance through the use of directed estimation and adaptive variable-length coding (VLC), while also incorporating run-length coding and delta coding for other pixel types. Furthermore, his system monitors performance parameters to dynamically adjust compression thresholds, optimizing pixel processing across multiple directions.

The second patent, "Method and apparatus for adaptive hybrid motion video compression," outlines a process for compressing motion video data effectively. In this method, a first frame of motion video is compared to a base frame, resulting in an altered base frame that integrates regions from both frames. This technique enables the creation of a motion compensation vector, streamlining the encoding process and improving overall efficiency.
