Title: Innovations of Robert W Parish

Introduction

Robert W Parish is an accomplished inventor based in Gaston, OR (US). He holds a total of 6 patents that showcase his expertise in generating advanced video test patterns and image processing techniques. His contributions to the field have significantly impacted the way video signals are generated and displayed.

Latest Patents

One of his latest patents is titled "System for generating text defined test patterns." This invention is directed towards a system that generates video test pattern signals from definitions contained in a text-based definition file. The definition file allows users to create generic definitions for test signals that can be interpreted to create test signals in various formats, raster sizes, color spaces, sample structures, frame modes, and bit depths. A parametric generator utilizes one or more engines to generate the desired test pattern from the definition file.

Another notable patent is "Image alias rejection using shaped statistical filtering." This invention addresses image alias rejection when converting a high-resolution rasterized waveform to a lower resolution for display. It employs a statistical filter that provides a shaped probability density function by combining outputs from multiple random number generators or using a corresponding look-up table to produce a dither signal. The statistical filter can be applied to one or both dimensional values for each data point of the high-resolution rasterized waveform, resulting in filtered values suitable for lower resolution displays.
