Latest Patents

François Nicolas holds a patent for a method of automatic determination of the contrast and brightness of a digital radiographic image. This method involves creating a histogram of the radiographed image, which is a real histogram. It utilizes a mathematical model of the image chain and the object obtained through calibration. The process determines two values of gray level, gray min and gray max, which help in delimiting a useful zone. The parts of the histogram below gray min and above gray max are suppressed to create a limited histogram. A set of rules is then applied to this limited histogram to determine the level of brightness (WL), while the contrast (WW) is derived from the brightness and possibly from user-selected parameters.
