Title: Innovations of Vijay Mahadevan
Introduction
Vijay Mahadevan is a prominent inventor based in San Diego, California. He has made significant contributions to the field of video coding, holding a total of four patents. His work focuses on enhancing the quality of video processing and improving user experience.
Latest Patents
One of his latest patents is titled "Temporal quality metric for video coding." This invention introduces techniques for evaluating the temporal quality of encoded video. Instead of relying solely on frame rate or motion activity, it uses the number of consecutive dropped frames as a basic estimation unit. The invention considers various factors of the human visual system, such as sensitivity to temporal quality fluctuations and motion activity, to provide a more accurate prediction of jerkiness that aligns with human visual response. This temporal quality metric can be utilized to estimate human perceived discomfort caused by temporal discontinuity in different video scenarios. The techniques can be applied in two modes: bitstream or pixel mode, allowing for enhanced evaluation and control of encoding or decoding characteristics.
Another significant patent is "Decoder-side region of interest video processing." This invention focuses on decoder-side region-of-interest (ROI) video processing. The video decoder assesses whether ROI assistance information is available. If it is not, the decoder defaults to decoder-side ROI processing. This method estimates the reliability of ROI extraction in the bitstream domain. Depending on the reliability, the decoder applies either bitstream domain ROI extraction or pixel domain ROI extraction. The invention also includes different ROI extraction processes for intra-coded and inter-coded data, utilizing color-based and coded block pattern-based generation methods, respectively.
