Latest Patents

One of his latest patents is an "Input modification system for multilevel dithering." This invention relates to an image processing system that utilizes quantization and dithering techniques. It enables an output device with a limited number of output levels to accurately reproduce images generated by an input device with a greater or equal number of input levels. The invention is versatile and can be implemented in various embodiments, including those that utilize memory devices, adders, comparators, or bit shifters. Additionally, it can be used with imaging systems that have bi-tonal, monochromatic, or color input and output devices.

Another significant patent is the "Method of quantifying the topographic structure of a surface." This method employs a fractal-based or 'patchwork' approach to analyze topographic data. It simulates covering a specimen's surface with triangular patches to determine the relative surface area based on patch size or scale of observation. The method calculates total measured area values and relative area values, which help distinguish between scales best described by Euclidean and fractal geometry.
