Latest Patents

Kottayil's latest patents include innovative methods for improving video signal quality. One of his patents, titled "Up-conversion to content adaptive perceptual quantization video signals," involves computing minimal noise levels over input codeword bins based on image content. This method adjusts these noise levels to generate approximated minimal noise levels of a higher bit depth, ultimately reshaping input images into output images with improved quality.

Another significant patent is "Piecewise-linear inter-layer predictor for high-dynamic range video coding." This invention enhances the dynamic range of HDR signals by applying a piecewise-linear inter-layer predictor and a residual masking operator. The prediction function is generated based on a computed scene-significance histogram, which indicates where coding artifacts are most likely to occur. This innovative approach takes into account bit rate constraints for the enhancement layer, ensuring optimal video quality.
