ABSTRACT:
A generalized grain ruler incorporating a plurality of uniform patches representing a range of granularities, each patch being a perceptually distinct representation of graininess spaced at perceptually uniform intervals and recorded in an increasing sequence of graininess. A method for producing a generalized grain ruler for the measurement, by comparison of, grain in a reference imaging system generated image, comprising, the steps of:
