Latest Patents
Arun Raj holds two notable patents that reflect his innovative approach in video codecs:
1. **Adjustable Trade-off Between Quality and Computation Complexity in Video Codecs**
This patent describes a method involving the generation of a backward reshaping mapping table as an inverse of a forward reshaping mapping table. The process includes updating this mapping table by replacing content-mapped luminance codewords with forward reshaped luminance codewords, which are generated through a luminance forward mapping. This technology enables the generation of reconstructed images from forward reshaped images, thereby enhancing the efficiency of video signal encoding.
2. **Reducing Banding Artifacts in Backward-Compatible HDR Imaging**
In this patent, methods and systems are outlined for mitigating banding artifacts when displaying HDR images reconstructed from coded reshaped images. By integrating noise into dark and mid-tone regions and modifying backward reshaping functions in highlight areas, this innovation significantly enhances image quality. Arun provides a technique using simulated film-grain noise to achieve these improvements.
