Latest Patents

Vinay Sathe's latest patents focus on the reduction of noise visibility in digital video systems. The first patent addresses the effects of noise in a video processing system, resulting in improved image quality. A digital video signal containing a luminance component in Y color space is processed by increasing the amplitude of the luminance data in accordance with a nonlinear transfer function. This process reduces low-amplitude components of the luminance signal, which in turn minimizes quantization errors in transform coefficients produced by a spatial compression routine in a video encoder. Inverse operations are performed at a video decoder to recover the original luminance data. The invention effectively reduces quantization noise, which is particularly noticeable as dust-like variations in luminance intensity in otherwise darkened regions of a video image. A decoder apparatus is also presented in this patent.
