Latest Patents

Parra's latest patents include groundbreaking methods for video compression. One of his patents, titled "Techniques for Video Compression," discloses a method where color differences are calculated between a current video frame and a motion-predicted version of that frame. This method is based on the human visual system's ability to perceive color differences, allowing for the discarding of unnecessary information in a difference frame.

Another notable patent is "Video Compression Using Perceptual Modeling." This patent outlines techniques for compressing video streams by converting frames from a source color space to a perceptual color space. It involves calculating a delta frame between the current and motion-predicted frames, determining input color difference values, and creating a tone-mapped color difference image. The process culminates in a modified delta frame that can be transformed, quantized, and encoded for efficient video transmission.
